摘要

A device for opening and shutting in two directions a lid (2) disposed rotatably on an opening of a box body (1) includes a pair of rotary shafts (4) and a pair of lock shafts (7) severally disposed in opposite lateral parts of the opening of the box body, coil springs (8) for interconnecting the rotary and lock shafts (4, 7) on the respective sides thereof and urging the lock shafts (7) toward the corresponding rotary shafts (4), and an operating member (13) for causing the lock shafts (7) to be moved away from the corresponding rotary shafts (4) against the resilient force of the springs (8). The opposite lateral parts of the lid (2) have first engaging holes (10) for engagement with the rotary shafts (4) and second engaging holes (11) for engagement with the lock shafts (7) severally formed therein. The springs (8) produce a pressing action to enable the lock shafts (7) to be independently released from the corresponding second engaging holes (11).
