Claims

[Scope of utility model registration request]

The lid body is pivotally attached to the main body so as to be openable and closable at a predetermined angle, and is biased in the opening direction by a torsion bar inserted through the center of the pivot, and is locked in the closed state by a locking member against the biasing force. In the device, a main body has a pair of shaft holes that are bored oppositely in the left and right side plates, and some of which communicate with the outside through a slit, and holes are bored in the left and right hanging portions corresponding to the shaft holes on the main body side. and a lid body having a pair of shaft holes that communicate with the outside through a slit through which the torsion bar can be inserted, and a side plate on the body side and a hanging part on the lid body side, and a holding member having concentric pivot shafts with an oval cross section protruding from both sides that are loosely fitted into the shaft holes on the lid body side, and a fixing pin that connects the holding member and the lid body in a relatively non-rotatable manner. The opening/closing device is characterized in that the pivot of the holding member has a parallel plane portion having an oval cross section that can be inserted into the slit of the main body, and a center hole through which the torsion bar can be inserted.
