Claims

[Scope of utility model registration request]

The mounting frame body for attaching the seat plate etc. of a chair,
It is composed of a top plate part and a fitting part below the top plate part that supports the upper outer periphery of the gas spring at an appropriate gap, and has a control valve push rod projecting upward from the upper end of the gas spring at the tip. At the midway point in the longitudinal direction of the operating rod that is pressed downward, a rotating support shaft is provided on both left and right sides so as to intersect with the longitudinal axis of the operating rod. A pair of upwardly open bearing parts that support both ends of the rotation support shaft of the operating rod from below are provided at the portion, and between the pair of bearing parts, the tip of the operating rod is inserted from diagonally above. A device for attaching a gas spring operating rod, characterized in that a guide piece is provided that can be inserted toward the fitting portion and prevents the operating rod from coming off when the distal end side of the operating rod is rotated upward by a substantially predetermined angle.
