PROBLEM TO BE SOLVED: To provide a vehicle seat reclining device that enables adjustment of a tilt angle by one operation system and fixed point return by the pull-up operation, and has a high setting degree of freedom about the return position.SOLUTION: A first memory member 51 regulates the radial direction movement of an engagement part 72 accompanying the lock operation of each lock member constituting a recliner 11 by an engagement part 72 of a second memory member 52 coming into abutment with a peripheral wall 55. Also, the first memory member 51 is integrally turned with a first turning member 21 in the coaxial position with the first and second turning members 21, 22 constituting the recliner 11 by the engagement between the peripheral wall 55 and the engagement part 72 of the second memory member 52 coming into abutment with the peripheral wall 55. Then, the first memory member 51 permits the slide of the engagement part 72 along the extension direction of the peripheral wall 55 in the state where the integral turning with the first turning member 21 is regulated by a turning restriction mechanism 60.SELECTED DRAWING: Figure 2 |
