When attaching to the cover 7, when the second cover 9 rotates to the locked position by the locking device 19, the protrusion 21 rides on the protruding piece 21 a of the locking portion 21. Thereafter, when passing through the protruding piece portion 21a, the second cover 9 suddenly moves downward, the open end of the second cover 9 comes into contact with the protruding piece portion 21a again, and the sensation at the time of this contact is felt. It is transmitted to the operator's hand and senses that the second cover 9 has rotated to the locked position. In addition, if the protrusion 61 is provided on the base plate 27 side, since it is made of metal, wear and damage can be prevented over a long period of time.

  The procedure for covering the spare tire cover 3 configured as described above with the spare tire 5 will be described.

  First, the spare tire 5 is accommodated in the first cover 7, and the spare tire 5 and the first cover 7 are attached to the outer surface of the back door 1 a of the RV vehicle 1 with fixing bolts. At this time, the contact / engagement piece 59 of the cover member 53 of the engagement / disengagement operation tool 23 is in contact with the engagement piece 57 of the base plate 27 from the outside as shown by a solid line in FIG.

  Next, the second cover 9 is put on the first cover 7. At this time, the engagement piece 57 abuts on the upper surface of the protruding piece portion 21a of the locking portion 21 on the first cover 7 side as indicated by a virtual line in FIG. 10, and as indicated by a virtual line in FIG. The insertion portion 15 a of the second engagement tool 15 contacts the open end of the first cover 7.

From this state, the second cover 9 is rotated in the circumferential direction. When the second cover 9 is rotated to the locked position by the locking device 19 as shown in FIG. 1, the protrusion 61 of the second cover 9 passes through the protruding piece 21a of the locking portion 21, and the feeling at that time is felt. Communicating to the operator's hand, the operator senses that the second cover 9 has been rotated to the locked position. As a result, the second engaging tool 15 slides on the open end of the first cover 7 in parallel with the movement of the locking device 19 to the locking position as shown by the phantom line in FIG. Then, it falls into the guide recess 11b of the first engagement tool 11, and the insertion portion 15a of the second engagement tool 15 is inserted from the guide recess 11b of the first engagement tool 11 into the engagement groove 11a. The first cover 7 penetrates in the radial direction. Thereby, both the engagement tools 11 and 15 are engaged with each other, and the second cover 9 is prevented from being detached from the first cover 7. In this state, as shown in FIG. 9, the convex portion 11 c of the first engaging tool 11 abuts on the inner peripheral surface of the second opening 9 a of the second cover 9 and the abutting portion of the second engaging tool 15. 15b is in contact with the base of the first engaging tool 11 and the back cover in the radial direction of the second cover 9 is prevented.

  Thereafter, the cover material 53 is moved away from the second cover 9 as indicated by phantom lines in FIG. 2 (at this time, the link plate 39 rotates clockwise about the shaft 41), The cover member 53 is rotated clockwise around the shaft 49, and the contact engagement piece 59 is engaged with the contact piece portion 21b of the locking portion 21, as indicated by a solid line in FIG.

  Thereafter, when the upper end of the cover member 53 is pressed toward the outer surface of the second cover 9, the link plate 39 rotates counterclockwise about the shaft 41, and the entire cover member 53 is as shown in FIG. The second cover 9 is pressed against the outer surface by the torsional force of the torsion spring 51, and the contact piece 21 b of the locking part 21 is contacted with the contact engagement piece 59 of the engagement / disengagement operation tool 23 and the engagement piece 57 of the base plate 27 The second cover 9 is prevented from rotating in the circumferential direction. In this state, the upper end portion of the cover material 53 is biased to the outside of the second cover 9 by the twisting force of the torsion spring 51. At this time, the shaft 49 moves through the long hole 39b in a direction away from the upper end portion of the long hole 39b, the compression spring 47 is compressed, and the engagement / disengagement is supported by the compression force (reaction force). The cover member 53 of the operation tool 23 moves upward, and the contact engagement piece 59 of the cover member 53 is pressed against the protruding piece portion 21a of the locking portion 21 from below. Further, the locking protruding piece 31 passes through the rectangular opening 53 b of the cover material 53 and protrudes to the outside. Thereafter, as shown by the phantom line in FIG. 3, the locking rod 33a of the padlock 33 is inserted into the key hole 31a of the locking protruding piece 31 protruding from the rectangular opening 53b to maintain the locked state. The installation and storage work of 3 is finished. When the spare tire 5 is taken out from the spare tire cover 3, the operation may be reversed.

Thus, in this embodiment, the first engagement tool 11 is provided on the peripheral edge of the first opening 7a of the first cover 7, and the second engagement is performed on the peripheral edge of the second opening 9a of the second cover 9. The first cover 7 is provided with a locking portion 21 and the second cover 9 is rotated in the circumferential direction. The engagement tool 15 is engaged with the first engagement tool 11, and the engagement / disengagement operation tool 23 is engaged with the locking portion 21 in this state. Accordingly, when the second cover is rotated and the second cover 9 is rotated to a predetermined position, it is only necessary to operate the engagement / disengagement operation tool 23 to prevent the rotation, so that the spare tire cover 3 is attached to the spare tire 5. It can be reliably and quickly covered. When the spare tire 5 is removed, the engagement / disengagement operation tool 23 is removed from the locking portion 21, and then the second cover 9 is rotated in the circumferential direction so that the second engagement tool 15 is moved to the first engagement tool. Therefore, it is possible to remove the spare tire cover 3 and the spare tire 5 reliably and promptly. Furthermore, by inserting the insertion portion 15 a of the second engagement tool 15 into the engagement groove 11 a from the guide recess 11 b of the first engagement tool 11 and penetrating the engagement groove 11 a in the radial direction of the first cover 7. The second cover 9 can be restricted from moving in the direction along the center line of the second cover 9.

  Further, in this embodiment, the convex portion 11c of the first engagement tool 11 is brought into contact with the inner peripheral surface of the second opening 9a of the second cover 9, and the contact portion 15b of the second engagement tool 15 is made to contact. The first cover 11 can be brought into contact with the second cover 9 to prevent the second cover 9 from rattling in the radial direction.

  Further, in this embodiment, the protrusion 61 is provided on the second cover 9, and the fact that the second cover 9 has rotated to the lock position is a feeling when the locking portion 21 on the first cover 7 side passes the protrusion 61. Since it can be known, the locking device 19 can be reliably locked at the locked position.

  Furthermore, in this embodiment, the locking device 19 is constituted by the engaging portion 21 provided on the first cover 7 side and the engaging / disengaging operation tool 23 provided on the second cover 9 side, and the engaging / disengaging operation tool described above. 23 is detachably engaged with the locking portion 21 to prevent the rotation of the second cover 9 in the circumferential direction, while the engagement / disengagement operation tool 23 is separated from the locking portion 21 and retreated. Since the rotation in the direction is allowed, the structure of the lock device 19 is simplified to the extent that the engagement / disengagement operation tool 23 has both the rotation prevention function and the rotation permission function of the second cover 9. Can do.

  Furthermore, in this embodiment, since the engagement / disengagement operation tool 23 is urged by the torsion spring 51 and engaged with the engagement portion 21, the engagement / disconnection operation device 23 is engaged with the engagement portion 21. Thus, the rotation of the second cover 9 can be prevented. Thereby, the locking function of the locking device 19 can be further improved.

  In addition, in this embodiment, the abutment engagement piece 59 of the engagement / disengagement operation tool 23 is pressed against the protruding piece portion 21a of the locking portion 21 from below by the spring force of the compression spring 47. In the state where the tool 23 is engaged with the locking portion 21, the back cover of the second cover 9 can be eliminated.
