1. A lid opening/closing device comprising:
a lid box provided with an opening;
a lid configured to be opened/closed between a closed position at which the lid closes the opening and an opened position at which the lid opens the opening; and
an opening/closing mechanism configured to open/close the lid with respect to the lid box, wherein
the opening/closing mechanism includes a link interposed between the lid box and the lid,
the link includes
a main arm rotatably supported on the lid box at one main arm end portion thereof, rotatably supported on the lid at another main arm end portion thereof, and configured to transmit an externally applied opening/closing driving force to the lid, and
an auxiliary arm rotatably supported on the lid box at one auxiliary arm end portion thereof, rotatably supported on the lid at another auxiliary arm end portion thereof, and 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 provided to the other main arm end portion, extending in a direction parallel to a rotation axis on the other main arm end portion side, and configured to come into contact with a back surface side of the lid at the opened position of the lid to restrict the main arm from rotating to an open side,
the lid includes a lid-side restriction portion provided on the back surface side thereof and configured to come into contact with the arm-side restriction portion at the opened position of the lid to restrict the main arm from rotating to the open side, and
an axial length of the arm-side restriction portion is longer than an axial length of the one main arm end portion.
