Abstract:
[Problem] With respect to a vehicle seat, reducing the drive force for expanding and contracting the seat. [Solution] A vehicle seat (1) comprises: a first frame (15); a second frame (16) that is movably supported, in relation to the first frame, on a first side and a second side opposing the first side; and an actuator (30) that moves the second frame, in relation to the first frame, to the first side and the second side. The actuator (30) comprises: a first actuator (31) that biases the second frame to the first side; a second actuator (32) that biases the second frame to the second side; and a control device (33) that controls the biasing forces respectively generated by the first actuator (31) and the second actuator (32). Each of the first actuator (31) and the second actuator (32) may have a fluid bag (35, 36) to and from which the control device (33) supplies and discharges compressed air.
