摘要： In a steering device according to an aspect of the present disclosure, a driven cam includes a lock position restriction surface with which a cam portion of a drive cam engages in a locked state and a release position restriction surface that is provided to be separated front the lock position restriction surface in a bolt circumferential direction and that engages with the drive cam in the bolt circumferential direction in an unlocked state. The cam portion includes a sliding surface that faces the driven cam in the unlocked state and a flank surface that faces the release position restriction surface in the bolt circumferential direction. The angle of the flank surface with respect to the bolt circumferential direction is smaller than the angle of the release position restriction surface with respect to the bolt circumferential direction.

摘要： A water pump includes a support portion provided with a bearing hole, and a pulley which is provided at one end of a rotation shaft and which is formed in a cylindrical shape with a bottom. The support portion includes an annular small-diameter portion provided with the bearing hole at the center, and an annular large-diameter portion. At least a part of the small-diameter portion is located at the pulley side relative to the large-diameter portion. An annular first clearance is formed between the cylindrical portion of the pulley and the large-diameter portion. A second cylindrical portion is provided on the bottom portion of the pulley. An annular second clearance is formed between the second cylindrical portion and the small-diameter portion.

摘要： A control valve includes a casing, a valve body, and a seal cylinder member. The casing has an inlet and an outlet. The valve body is rotatably disposed inside the casing, and has a peripheral wall portion formed with a valve hole providing communicating between the inside and the outside. One end portion of the seal cylinder member communicates with a downstream side of the outlet, and a valve sliding contact surface is provided at the other end portion. A protruding height of the other end portion of the seal cylinder member continuously changes in a circumferential direction thereof to conform to a shape of an outer circumferential surface of the circumferential wall portion. A region of the other end portion of the seal cylinder member where the protruding height is lower is provided with a thick portion that is thicker than other portions and reaches the valve-sliding contact surface.

摘要： According to an aspect, there is provided a steering device including a pipe, a housing, a telescopic mechanism, and a load absorbing mechanism. The load absorbing mechanism includes an EA plate disposed in the pipe, a guide plate disposed in a telescopic movable portion, and overlapped with the EA plate, and a connection member connecting the EA plate and the guide plate to each other. Dimensions of the load absorbing mechanism are set so that a load applied between the connection member and the EA plate is lower than a load applied between the connection member and the guide plate.
