Before assembling the spare tire 300 as shown in FIG. 4A, the locking lever 100 is in a position where the locking lever 100 is separated through the open side 112 of the housing 110 by the elastic force of the torsion coil spring 120. . Since the locking lever 100 has moved out of the housing 110, even when the wire 150 is pulled, the locking lever 100 is caught by the locking lever holder 200 so that the housing 110 is inserted into the locking lever holder 200. It can't be.

When the spare tire 300 is assembled on the tire bracket 180 as shown in FIG. 4B, the housing 110 is moved downward by the load of the spare tire 300, and the washer 140 is relatively in the housing 110. Pushed up from. Therefore, the washer 140 comes into contact with the bottom surface 106 of the locking lever 100 and transmits the elastic force by the compression coil spring 160 to the locking lever 100 through the washer 140. Therefore, the locking lever 100 is rotated about the rotation axis by the elastic force transmitted to the locking lever 100 so that the locking lever 100 which is separated out of the housing 110 is located inside the housing 110.

As shown in FIG. 4C, after the locking lever 100 is positioned inside the housing 110 by the load of the spare tire 300, the wire 150 is wound up by the power transmission device 400. At this time, the spare tire 300 including the housing 110 is raised by the force transmitted to the wire stopper 170. Since the locking lever 100 is present inside the housing 110, the locking lever 100 and the locking The housing 110 is inserted into the locking lever holder 200 without interfering with the lever holder 200.
