Further, in this closed state, the arm portion 71 is inclined forward, and the connecting portion 72 is positioned relatively in front of the lower side, that is, close to the damper device 46. In this state, the damper device 46 is in a state in which at least a part of the operation cord 46b is drawn into the damper main body 46a by the urging force of the coil spring.

  From this closed state, when the occupant operates the operating body 75 and retracts the latch body 76 to release the engagement, the lid 14 moves so that the upper part moves downward from the near side due to its own weight. It rotates to the 2nd position which is a rotation limit position, and as shown in FIG.1 (b), the cover body 14 will open and the opening part 23 of the box main body 12 will be in the open state. In this turning process, the arm portion 71 attached to the lid body 14 is turned, and the connecting portion 72 of the arm portion 71 is moved from the third position to the fourth position on the rear side, that is, connected. When the portion 72 is separated from the damper device 46, the operation cord 46b in which the hook portion 46c is hooked and connected to the connecting portion 72 is pulled out from the inside of the damper main body 46a. At this time, the operation string 46b of the damper device 46 is pulled forward with the rotation of the arm portion 71, that is, the movement of the connecting portion 72, and the lid body 14 is braked by the resistance of the air received by the top, that is, from the natural state. In a state where it is decelerated, it turns slowly.

  When the lid 14 is fully opened to the rotation limit position, which is the second position, each part on the lid 14 side faces each part on the box body 12 side as described below. One, a plurality of places, or all places come into contact with each other to hold the lid 14 in the rotation limit position. That is, in this rotational limit position, the rotating body side abutting portion 63 of the base plate portion 62 of the lid body 14 faces or abuts against the body side abutting portion 33 of the bottom portion 25 of the box body 12, and the lid body side of the lid body 14 The stopper portion 68 faces or abuts against the bottom 25 of the box body 12, the tip portion of the arm portion 71 faces or abuts against the stopper portion 52 of the box body 12, and the lid body 14 is held at the rotational limit position. .
