A latch mechanism of a vehicle seat reclining device includes a plurality of latch holes formed in a rail along a central axial line, a slider hole penetrating through a slider so as to face the respective latch holes, a support portion provided on the slider, and a movable portion displaceably supported by the support portion and having a latch projection that is engageable with the respective latch holes while passing through the slider hole. A clearance is defined in the direction of the central axial line between the slider hole and the latch projection. One or more shock absorbing members is (are) provided on opposing first and second inner surfaces of the slider hole and abut against the latch projection while being resiliently deformed to suppress the generation of undesirable rattling noise in case a force causes the latch projection to oscillate within the engaged latch hole.
