In the present embodiment, the through hole 610d is a rectangular hole, but the shape of the hole is not limited to this, and any shape can be used as long as the flange portion 711 of the hook lever 71 can be inserted.

(Operation)
Next, the operation of the lock mechanism 7 will be described with reference to FIGS.

  FIG. 9 is a cross-sectional view for explaining the operation of the lock mechanism 7 when removing the charging port cover 5, (a) showing the locked state, and (b) showing the unlocked state. .

  As shown in FIG. 8A, when the locking mechanism 7 is in the locked state, the flange portion 711 of the hook lever 71 is positioned in the recess 610 through the through hole 610d of the case portion 61 in the waterproof case 6 and is on the lid side. The striker 33 is restrained. At this time, the release lever 74 is in a state of disengagement between the hook lever 71 and the release lever 74 because the protruding portion 741 is located at the retracted position. In this locked state, as shown in FIG. 9A, the cover-side striker 55 of the charging port cover 5 is a latch of the lid lock device 9 fixed to the support 900 provided inside the vehicle body 1. It is restrained by 91.

  When the lid lock device 9 is unlocked by an unillustrated open lever arranged in the passenger compartment, as shown in FIG. 9B, the latch 91 of the lid lock device 9 releases the cover-side striker 55. The charging port cover 5 is pushed up in the opening direction (arrow X direction) by the rotational force of the latch 91.

  Then, the waterproof case 6 is pushed up in the arrow Y direction with respect to the release lever 74 by the biasing force of the first coil spring 721. In other words, as shown in FIG. 9B, the release lever 74 is displaced relative to the waterproof case 6 from the retracted position to the protruding position. As a result, the engaging portion 742 of the release lever 74 engages with the engaged portion 713 of the hook lever 71, so that the hook lever 71 rotates from the restraining position toward the releasing position by a predetermined angle.

  Then, since the lid-side striker 33 is released from the collar portion 711 of the hook lever 71, the lock of the charging port cover 5 with respect to the lid 3 is released, and as shown in FIG. 9B, the lid 3 is opened ( It is possible to move in the direction of arrow Z). As a result, the charging port cover 5 can be detached from the vehicle body 1 and the lid 3.

Thus, it arrange | positions in the state inclined with respect to the horizontal direction. Accordingly, since the bottom surface 610a of the recess 610 is an inclined surface inclined with respect to the horizontal direction, even when the recess 610 is submerged, the water is reliably discharged from the opening 610e along the bottom surface 610a.

(Effect of embodiment)
(1) Since the charging port cover 5 according to the present embodiment includes the waterproof case 6 that houses the lock mechanism 7, the waterproof property of the lock mechanism 7 can be improved. As a result, for example, it is possible to prevent malfunctions caused when water adheres to the lock mechanism 7 and freezes.

(2) Since the through hole 610d in the recess 610 of the waterproof case 6 is provided at a position spaced a predetermined distance from the bottom surface 610a of the recess 610 upward, the through hole 610d is at the position of the bottom surface 610a of the recess 610. Compared with the case where it is provided, it is possible to more reliably prevent water from entering the waterproof case 6 from the through hole 610d.

(3) Since the recessed part 610 of the waterproof case 6 has the opening part 610e opened in the direction along the vehicle front-back direction, for example, even when it is immersed in the bottom face 610a of the recessed part 610, it is from the opening part 610e. It is possible to drain to the outside.

  While the embodiments of the present invention have been described above, the embodiments described above do not limit the invention according to the claims. In addition, it should be noted that not all the combinations of features described in the embodiments are essential to the means for solving the problems of the invention.

    The present invention can be appropriately modified and implemented without departing from the spirit of the present invention.
