Abstract: The ball joint includes a metal ball stud which includes a ball section and a resin housing which rotatably supports the ball section of the ball stud. A limiting member configured to limit molding shrinkage of the housing is embedded in the housing at an interval with respect to an equatorial section of the ball section such that the limiting member is positioned to surround at least the equatorial section of the ball section.

Abstract: A coil spring includes a wire shaped to be helical, and is compressed between an upper spring seat and a lower spring seat. The coil spring includes an upper portion and a lower portion. A positive pitch winding end portion is formed on the upper portion of the coil spring. A terminal-point-strong-abutting-portion is formed at a distal end of the winding end portion. The terminal-point-strong-abutting-portion is in contact with the upper spring seat at one point at a position deviated to an inner side of a vehicle with respect to a coil central axis. On the lower portion of the coil spring, an end turn portion which contacts the lower spring seat is formed.

Abstract: A joined body includes: a thin plate including through holes; first members each including: a base portion and a protruding portion inserted into one of the through holes; and a second member placed oppositely to the base portion via the thin plate and made of a material that is of a same kind as a material of the first members. The thin plate is made of a material having a specific gravity smaller than the materials of the first and the second members. The second member and an end portion of the protruding portion are connected together by melt-solidification. A post-joining hardness difference in a range of 30% along a direction orthogonal to a joint interface between the second member and the protruding portion, the range being centered on the joint interface, is equal to or less than 90% of a pre-joining hardness difference.

Abstract: A nozzle cleaning apparatus has one cleaning liquid outlet to which a nozzle is attached, and the other cleaning liquid outlet to which a cleaning attachment is attached. The cleaning attachment includes a nozzle cover, and a cleaning holder attached to the nozzle cover. A cleaning chamber is formed in the nozzle cover. A cleaning liquid inflow chamber, an outer cleaning liquid ejection port, and a cleaning liquid discharge hole are formed in the cleaning holder. A cleaning liquid ejected in a first direction from the nozzle and a cleaning liquid ejected in a second direction from the outer cleaning liquid ejection portion toward the nozzle collide with each other near discharge portions inside the cleaning chamber.

Abstract: In a vehicle seat, a second parallel link mechanism is actuated in order to adjust an vertical position of a seat body with respect to a vehicle body, such that a first parallel link mechanism is moved up or down together with the seat body with respect to the vehicle body. In order to recline a seatback as an integral unit with a seat cushion, the first parallel link mechanism and the second parallel link mechanism are actuated such that an upper link is maintained in a predetermined orientation. The upper link is restricted from rotating relative to the armrest, and so the armrest is also maintained in a predetermined orientation.

Abstract: A power seat device is configured to acquire a target associated position of a tilted position, corresponding to a current position of a seatback for allowing the seatback to reach an end position in a reclining range, and a seat to reach an end position in a tilting range simultaneously. Outputs of a reclining motor and a tilting motor are adjusted so that the tilted position coincides with the acquired target associated position.
