Claims

[Scope of Claim for Utility Model Registration] (1) A rotating seat in which the underframe of the seat main body is configured to be able to rotate forward and backward via a rotating device on a footrest fixed to the floor, with a footrest at the rear of the said underframe. The proximal end of the supporting arm constituting the device is pivotally mounted so as to be rotatable in the vertical direction, and an elastic member is interposed in the pivoting portion to constantly flip up and urge the footrest device upward, and at least A recess is formed on the outer periphery of the proximal end of one of the support arms, and a stopper is formed that can be freely inserted into and removed from the recess when pressed downward, and the stopper is linked to a pedal for releasing the rotation of the rotating seat. 1. A foothold device for a rotating seat, characterized in that the foothold device is connected to one relay member for a rotating seat, and is configured so that the locking operation of a stopper with respect to the foothold device can be released in conjunction with the operation of the pedal. (2) A plurality of foothold devices configured on the underframe are each connected to the single relay member, and the locking operation for each foothold device can be released at the same time by operating a pedal. A footrest device for a rotating seat according to claim 1. (3) The footrest device for a rotating seat according to claim 1, wherein the support arm is pivotally attached to the underframe using a bolt and nut, and the tightening force thereof can be adjusted.
