  • Patent number: 10052978
    Abstract: By a contact of an engagement portion of a second memory member to a circumferential wall portion of a first memory member, the engagement portion is restricted from moving in a radial direction in accordance with a lock operation of lock members. By an engagement of the circumferential wall portion of the first memory member with the engagement portion of the second memory member that is in contact with the circumferential wall portion, the first memory member integrally rotates with a first rotary member on a same axis of the first and second rotary members. In a state where a rotation limiting mechanism restricts the first memory member and the first rotary member from integrally rotating with each other, the first memory member allows the engagement portion to slide along a longitudinal direction of the circumferential wall portion.

  • Patent number: 9849811
    Abstract: A vehicle seat reclining device is disclosed. An operation mechanism allows a second memory member to engage with and disengage from a first memory member, and locks and unlocks a lock member in conjunction with the engagement and disengagement. When the first memory member is in a predetermined rotational position relative to the second rotating member, the second memory member is inserted into an engagement slot provided in the first memory member, thereby restricting rotation of the first memory member relative to the second rotating member. The operation mechanism includes a link member that is linked to the second memory member inserted into a guide hole provided in a plate-shaped member. In the thickness direction of the plate-shaped member, the link member is arranged on the same side of the plate-shaped member as the first memory member.
