PROBLEM TO BE SOLVED: To smoothly actuate a mechanism part for interlocking backrest reclining rotation with switching of actuation states of a lock mechanism. SOLUTION: In the lock operation mechanism 5, the lock mechanism 7 to a car body floor is canceled by backrest reclining operation. In accordance with backrest reclining rotation, an operation cable C1 is pulled, and a second link 30 is pushed back by a regulation pin 40 as the rotation advances, thus pushing a first link 20 in a clockwise direction to switch the lock mechanism 7 to be canceled. As the rotation further advances, engagement of the second link 30 with the regulation pin 40 is released. As pushing relation between both is inverted, the lock mechanism is switched into an engagement lockable state. As pull of the operation cable C1 is released, the second link 30 pushes the regulation pin 40 back to return to an initial rotation position, and the regulation pin 40 is returned to an initial position after it is pushed back.
