Claims

[Scope of utility model registration request]

a lid whose rear edge is pivotally attached to the rear edge of the opening; a candlestick whose front end can freely protrude from the front edge of the lid and be slidable along the upper surface of the lid; and a front edge of the opening. a locking device provided on the top surface of the lock rod that can be freely secured to the front end of the lock rod; a drive plate with the rear end of the lock rod pivoted to a non-spindle support that is horizontally rotatably supported on the top surface of the lid; A stopper protrusion protrudes from the top surface and engages with a rotation restriction notch provided on the periphery of the drive plate to restrict the range of rotation of the drive plate, and one end is fixed to the collar protrusion and the other end is driven. A reversing biasing spring is fixed to a non-axial fulcrum of the plate and reverses the direction of the rotational biasing force approximately at the center of the rotational range of the drive plate, and the reversal biasing spring is configured to reverse the direction of the rotational biasing force approximately at the center of the rotational range of the drive plate. A lid opening/closing device in which the direction of the rotational biasing force of a biasing spring matches the rotational operation direction.
