A suspension seat, including: a lower side member that forms a vehicle lower side of a suspension; an upper side member that forms a vehicle upper side of the suspension, and that is configured to support a vehicle seat body from the vehicle lower side; a suspension link mechanism that includes a vehicle lower side portion coupled to the lower side member and a vehicle upper side portion coupled to the upper side member, and that undergoes displacement so as to displace the upper side member along a vehicle vertical direction; a linear displacement section that is provided at the suspension link mechanism and is configured to undergo linear displacement in conjunction with displacement of the suspension link mechanism; and a locking mechanism that immobilizes the linear displacement section so as to immobilize displacement of the suspension link mechanism.

A favorable appearance can be achieved using a simple configuration, even when the configuration is provided with a back shell that moves up and down relative to a back frame. In a vehicle seat, the back of a seated person is adapted to be supported by a movable back shellthat is supported so as to be capable of moving in an up-down direction relative to a back frame. A non-movable back shellthat is attached so as to be incapable of displacement relative to the back frameis disposed on a back face side of the movable back shell, and the back frameis covered by the non-movable back shell

The actuator mechanism of the present embodiment comprises the first cylinder, a rod protruding from the first cylinder to lift a hood and lock balls arranged along the outer periphery of the rod and digging into the rod when the rod is pushed back. The diameter of the lock balls and the lapping amount of the lock balls are within specific ranges.
