Thus, when a cushioning member (8) is interposed between a ball joint (40) and a rack bar storage part (13) of a housing 1 at a stroke end of the rack bar (3), the cushioning member (8) can be guided to the second inclined surface (832) side.

Further, if thermal expansion occurs in the retaining member (8), such thermal expansion is absorbed by a first elastic member (91) or a second elastic member (92), and thus there is no risk of a reduction, due to the thermal expansion, in the retaining properties of the retaining member (8) with respect to the ball bearing (7).

Provided is a resin molded body manufacturing method that increases variation in product shape of a resin molded body, and prevents electric conductor deformation and mold breakage. This resin molded body manufacturing method comprises: a mold preparation step for preparing a movable-side mold and a fixed-side mold; a positioning step for positioning an electric conductor in the fixed-side mold; a closing step for closing the molds and accommodating the electric conductor in the molds; an injection step for injecting a liquefied resin into the molds; a curing step for curing the resin inside the molds and fixing a part of the electric conductor to the resin; and an opening step for separating the movable-side mold from the fixed-side mold. In the mold preparation step, a mold having a groove that accommodates at least a portion of the electric conductor is prepared. The groove has a groove bottom wall having a bottom wall surface with which the electric conductor is brought into surface contact, and a pair of groove lateral walls having tapered surfaces that are inclined from the groove bottom wall so as to expand toward a groove opening provided in a position opposite the groove bottom wall. The height of the pair of groove lateral walls is half the distance between adjacent electric conductors.

Provided is a fuel injection control device that increases a driving current supplied to a plurality of fuel injection valves to a target valve opening current using a voltage application switch. Here, the fuel injection control device is provided with a control circuit that performs chopping control of the voltage application switch. Through the chopping control of the voltage application switch by the control circuit, a time required for the plurality of fuel injection valves to reach the valve opening current is made the same. Thus, a reduction in the fluctuation of injector valve opening timing between cylinders can be achieved.
The purpose of the present invention is to provide an internal combustion engine control device that makes it possible both to achieve stable combustion of an air-fuel mixture and to prevent damage to an ignition coil caused by heat production. A control device 200 for an internal combustion engine 100 that comprises an ignition plug 105 and an ignition coil 150 comprises: a temperature estimation unit 210 that estimates a coil temperature that is the temperature in and around the ignition coil 150 of the internal combustion engine 100; and an ignition control unit 220 that controls energization of the ignition coil 150 and thereby controls the current supplied to the ignition plug 105. The ignition coil 150 has an increase mechanism that increases the current being supplied to the ignition plug 105. The ignition control unit 220 controls the increase in current by the increase mechanism such that the increase is smaller the higher the estimated coil temperature.
Provided is a vehicle control device capable of ensuring control margin time required for avoidance control and performing collision avoidance control. The present invention provides a means and a device that: store recognition information on a two-wheel vehicle at the time of overtaking the two-wheel vehicle; on the occasion of turning left by a host vehicle at an intersection, read recognition information on two-wheel vehicles recognized in the past, judge the possibility of collision with the host vehicle, and calculate prediction recognition information; and when an obstacle is actually detected at the time of turning left by the host vehicle, immediately confirm that the obstacle detection is a re-detection of a moving body which was recognized in the past, by using the prediction recognition information calculated in advance; and perform avoidance control. Accordingly, control margin time for avoiding collision with an obstacle which comes from behind the host vehicle at the time of turning left and which is difficult to avoid can be ensured, and collision can be prevented.
This stereo camera device comprises: a storage unit that stores correlation information of a horizontal direction parallax error in relation to a perpendicular offset in a plurality of images captured, respectively, by a plurality of cameras through a refractive body that refracts light; a matching unit that matches a plurality of images by the plurality of cameras that captured the same subject, to determine the perpendicular offset of the plurality of images; a parallax error estimation unit that estimates the parallax error of the plurality of matched images on the basis of the perpendicular offset and the correlation information; and a distance calculation unit that corrects the parallax of the matched images using the parallax error.
