Has been. The cylinder support portion 79a is formed in a substantially U shape so as to guide the side portion of the cylinder lock 80 when the lid member 78 is closed. Thus, after the lid member 78 is closed, when the cylinder lock 80 is rotated by a key operation (not shown), the hook of the cylinder lock 80 is locked to the locking portion 79 and the lid member 78 is locked. Further, for example, even if another person forcibly shifts the lid member 78 left and right after locking to remove the hook of the cylinder lock 80 from the locking portion 79, the cylinder support portion 79 a is not closed when the lid member 78 is closed. Since the side portion of 80 is guided, the lid member 78 cannot be shifted in the left-right direction, and the hook of the cylinder lock 80 cannot be removed from the locking portion 79a. By configuring the lid member 78 of the front trunk 70 to be locked in this way, it is possible to improve the anti-theft property of the stored items in the front trunk 704, and the P-type lock member 75 can be provided permanently. .
Note that the lock member to be housed in the front trunks 73 and 74 is not limited to the P-type lock member 75 described above. Therefore, the lock member housing portion 76 also includes, for example, an articulated cycle lock, etc. It can be formed in a shape corresponding to various types of locking members. Also, the lock member gripping means 77 can be formed in a shape corresponding to the lock member to be stored.
