A seat reclining device includes a first bracket, a second bracket, a cam, and pawls moved in a radial direction and engaged with the second bracket. The pawls include outer teeth engageable with the second bracket. The second bracket includes an outer circumferential wall including inner teeth engaged with the outer teeth, and an inner circumferential portion. At least one of the pawls includes a first block and a second block shifted in an axial direction from the first block. The second block is formed integrally with the first block. The first block includes the outer teeth and a cam surface that contacts the cam. The second block includes a restriction surface that contacts the inner circumferential portion when the pawl moves toward the outer side. The cam surface and the restriction surface have the same planar structure.

Seat reclining device

A vehicular seat slide device is provided with a lower an upper rail, a lock member, a memory piece, a memory link, a slide member, and a stopper member. The memory piece is engaged with the upper rail and the lower rail. The memory link releases the lock member and the memory piece with urging force of a memory link urging member, and pivots in a releasing direction to press the lock member in a pivot direction and press the memory piece against the urging force of the memory piece urging member. The slide member releases the memory link with urging force of a slider urging member, and presses the memory link in the release direction by moving as a seat back is collapsed forward. After the seatback is collapsed forward and the upper rail is moved in a seat-rearward direction, the stopper member contacts the memory piece.

Vehicular seat slide device

A seat reclining device includes: a first bracket including an accommodating portion being open to an outer side of a seat in a width direction; a second bracket rotating with respect to the first bracket; a cam rotating with respect to the first bracket; a spring accommodated in the accommodating portion and biasing the cam; a pawl moved in a radial direction of the first bracket based on the rotation of the cam and engaged with the second bracket; and a cover covering the spring, wherein the cover is mounted on the accommodating portion and an outer surface of the cover on the outer side corresponds to an outer surface of the first bracket on the outer side or is positioned inside the outer surface of the first bracket in the width direction of the seat.
