PROBLEM TO BE SOLVED: To provide a novel and useful chair capable of smoothly executing lifting/lowering operation and reclining operation of a back and a seat without impairing rigidity despite a single actuator and, when backward reclining the back, appropriately avoiding its upper part from projecting rearward. SOLUTION: This chair is provided with the single actuator 5 provided in a fixed back part 1 and having an operating body 51 executing a prescribed reciprocating operation alone, and rigid bodies 6 having their one portions attached to the operation body 51; and the rigid body 6 is so constituted as to, when the operation body 51 moves in an upper part of a prescribed position, move its whole body in the prescribed direction along with the operation body 51 to liftingly drive the back 4 and the seat 3, when the operation body 51 lowers exceeding the prescribed position, swing the other portion in the direction (frontward) different from the prescribed direction to move the lower part of the seat 3 and the back 4, thereby executing the reclining operation interlocking the frontward movement of the seat 3 with the rearward movement of the back 4.
