Based on the relative posture of the engaging portion rotating integrally with the push rod with respect to the engaging hole, the engaging state where the engaging portion is engaged with the engaging hole of the lid and the non-engaging state where the engaging state is released. It is comprised so that a combined state may be switched.

  When the push rod is pushed into the lid against the urging force of the urging member and moves from the protruding position to the pushed position as the lid is closed, the fixing pin slides in the inclined groove of the push rod, and the push rod Rotates with axial movement. By this rotation, the engaging portion of the push rod is engaged with the engaging hole of the lid, and the lid is closed. At this time, as the push rod moves in the axial direction, the rotary arm also rotates, and the slide pin of the rotary arm is locked in the first locking groove, so that the push rod is held in the pushing position. Become.

  On the other hand, if the lid is further pushed into the lid when the lid is closed, the sliding contact pin of the rotating arm is detached from the first locking groove, and the rotating arm rotates and is pushed by the biasing force of the biasing member. The rod rotates with the axial movement from the pushing position to the protruding position. By this rotation, the engagement of the engagement portion of the push rod is released from the engagement with the engagement hole of the lid, and the lid is pushed in the opening direction by the axial movement of the push rod. Open state. In this state, the push rod is held at the protruding position by the sliding contact pin of the rotating arm being locked to the second locking groove portion in the guide groove of the guide member.
