A lid opening/closing device includes a lid box, a lid, and an opening/closing mechanism. The opening/closing mechanism includes, as a link interposed between the lid box and the lid, a main arm rotatably supported on the lid box at one main arm end portion thereof and an auxiliary arm configured to restrict a posture of the lid during opening/closing of the lid so as to keep the lid in a predetermined posture by rotating in conjunction with rotation of the main arm. The main arm includes an arm-side restriction portion configured to come into contact with a back surface side of the lid at an opened position of the lid to restrict the main arm from rotating to an open side. An axial length of the arm-side restriction portion is longer than an axial length of the one main arm end portion.

Lid opening/closing device

In a lid assembly structurewhich includes a base member, a lid, and an opening/closing mechanismand in which the opening/closing mechanismincludes a biasing member, during assembling of the base memberand the opening/closing mechanism, the biasing memberis guided by a guide portionwhich is a part of the opening/closing mechanism, and a state of the biasing memberis changed from a temporary assembled state where a second engagement endof the biasing memberand a temporary engagement portionengage with each other to a main assembled state where the second engagement endand a main engagement portionof a mating member engage with each other, thereby accumulating at least a part of a biasing force in the biasing member
