Claims

[Scope of utility model registration request]

(1) The front protrusion of each gas spring is pivotally attached to the lower front and rear positions of the fixed member attached to the pedestal via a rotating shaft, and the rear end of one gas spring is rotated by the fixed member. The rear end of the other gas spring is formed in an L-shape at the front part of the freely supported seat plate, and the horizontal end of the spring is rotatably supported by the fixed member, and is located near the bent part of the back arm. The fixing member is rotatably mounted, and a pair of actuating parts each having a cam part which is always elastically biased inwardly by a spring and which bulges outward in the lower part are mounted on the upper front and rear positions of the fixed member. The operation rods are arranged so as to be tiltable and opposite to each other, and have release pins of the gas springs facing each other on the outer surface of each operating member, and further have a handle portion at one end and two wisteria-shaped portions at the other end and extend in the left-right direction. The tip of the two-stepped portion is fixed to a rotary piece provided horizontally rotatably on the fixing member, and the two-stepped portion faces the following inner surfaces of the pair of actuating parts. 2. A chair comprising a guide plate attached to the fixing member, the guide plate having a guide hole that comes into contact with the handle portion and includes a horizontal portion that guides the handle portion in the front-rear direction and a vertical portion that guides the handle portion in the longitudinal direction.

(2) The chair according to claim 1, which is a registered utility model, wherein the rear part of the seat plate and the tip of the horizontal part of the back arm are commonly supported by a fixed member.

(3) A chair according to claim 1 or 2, wherein the operating member is made of synthetic resin and its upper end is attached to a fixed member so as to be movable back and forth.
