Claims

[Scope of utility model registration request]

The base end of the lid 2 is pivotally attached to the fixed frame 1 by a horizontal pivot 3, and the base end of a swing bracket 13 is pivotally attached to the distal end side of the lid 2 by a horizontal pivot 15. The mounting end 8 of the cylinder 7 of the gas damper 6 is pivoted to the tip of the swing bracket 13 on the opposite side of the horizontal pivot 3 with respect to the horizontal pivot 9, and the gas is The mounting end 11 of the rod 10 of the damper 6 is connected to the horizontal pivot 12
A tension member 21 is pivotally connected to the fixed bearing plate 5 by the cylinder 7, and the lid 2 is rotationally biased in the opening direction by the pressure of the gas sealed in the cylinder 7.
A mounting part 20 for the tension member 21 is provided on a fixed wall surface 27 located on the tip end side of the lid 2, and the tension member 21, which is tensioned when the lid 2 rotates beyond a specified angle, is mounted. A gas damper-driven lid opening/closing device installed between the section 20 and the mounting section 24.
