To individually set a displacement of a seat part between a sitting position and a standing position and also between a sitting posture and a standing posture.SOLUTION: A chair 1 includes: a link mechanism 10 to be extended/contracted on a vertical surface; a link mechanism 20 connected to the link mechanism 10 in a drive force transmittable manner; and a link mechanism 30 connected to the link mechanism 10 in a drive force transmittable manner. The chair also includes: a link mechanism part where an output link on an upper side of the link mechanisms 20, 30 is a common link; a seat part 40 arranged on the common link and having a seat surface; and a linear actuator 13 to give drive force to an input link of the link mechanism 10. The link mechanism 20 receives drive fore from the linear actuator 13 via the link mechanism 10, so as to move the seat part 40 between a sitting position and an upper standing position. The link mechanism 30 receives drive force from the linear actuator 13 via the link mechanism 10 so as to change the seat surface of the seat part 40 between a horizontal sitting posture and a standing posture where a front side is inclined downward.SELECTED DRAWING: Figure 2
