【Example】

Hereinafter, embodiments of the present invention will be described based on the drawings. (Example 1) A plan view of the main parts of the fastening member according to this embodiment is shown in FIG. 1, and a sectional view taken along the line II-II in FIG. is shown in Figure 2, and a cross-sectional view taken along the line III-III in Figure 1 is shown in Figure 3. FIG. 4 shows a side view when the fastening member is fastened, and a cross-sectional view of the fixing member portion when the fastening member is fastened. is shown in Figure 5.

[0008] The fastening member of this example connects the cylindrical boot of the constant velocity joint to the joint main body. It is for attaching to the body, and as shown in FIG. A band main body 1 having six first engaging claws 15 and one end at the other end 12 of the band main body. The fixing member 2 is physically provided and has a second engaging claw 25. The band body 1 is formed into a band shape by processing a single metal plate, and has one end portion 11. The predetermined length portion is narrower than other portions. One end of the band body 1 11 and at a position separated by a predetermined distance from the other end 12, there is a band main body. A pair of locking portions 13, 1 that locks the jig when pulling both ends 11, 12 of 1 3 is formed with a window-like opening. The one end portion 11 has a predetermined shape in the longitudinal direction. Six first engaging claws 15 are provided, which are formed at intervals. This first As shown in FIG. 2, the engaging claw 15 is formed by cutting a portion of a metal plate into a U-shape. Both are erected outward so that the cut portion is upwardly inclined toward the other end 12 side. It is formed by raising the

[0009] The fixing member 2 has a corner having a through hole 21 inside it by bending a metal plate. It is formed into a cylindrical shape. This fixing member 2 is inserted into the through hole 21 as shown in FIG. The other end 12 of the inserted band body 1 and its inner wall 22 are joined by spot welding. By fixing it, it is integrated with the band main body 1. Through hole 21 of fixing member 2 Inside, a band main body is provided between the outer wall 23 of the fixing member 2 and the other end 12 of the band main body 1. A space is formed through which one end 11 of the body 1 can be inserted. Then, the outside of the fixing member 2 A second engaging claw 25 that engages with the first engaging claw 15 is provided on the side wall 23 through the fixing member 2. It is provided to protrude into the through hole 21. This second engaging claw 25 is located at one end of the outer wall 23. Make two parallel cuts in the longitudinal direction from the end surface on the end 11 side, and Raise the notch part inward so that it slopes upward toward one end 11 side. It is formed by The length of the second engaging claw 25 in the inclination direction is the same as that of the fixed member 2. It is shaped so that it is longer than the space width between the outer wall 23 of the band body 1 and the other end 12 of the band body 1. has been completed.

0010 The fastening member of this embodiment configured as described above connects the boot to the constant velocity joint body. It is fastened as follows when installed on the First, as shown in Figure 4, attach the band body 1 to the outer circumference of the boot (not shown). The one end 11 is inserted into the through hole of the fixing member 2 so that the one end 11 is connected to the other end. so that they overlap on the outside of section 12. Next, attach the jig (not shown) to the pair of locking parts. 13, 13 until the band body 1 is tightened by a predetermined amount. 2 in the circumferential direction. Then, the one end portion 11 advances inside the through hole of the fixing member 2. As the first engaging claw 15 is pushed down by the second engaging claw 25, the second engaging claw is sequentially engaged. It passes through the claw 25 and returns to its original slanted shape after passing through. And as shown in Figure 5 At the position where the band body 1 is tightened by a predetermined amount, one of the first engaging claws 15 engages the second engaging claw. It engages with the claw 25. As a result, both ends 11 and 12 are not retracted from each other. and complete the fastening work. Note that the second engaging pawl 25 is used to tighten the fastening member after the fastening is completed. Due to the reaction force, the tip of the first engaging claw 15 is inserted into the base of the engaged first engaging claw 15. 2, the first engaging claw 15 is engaged more firmly with the first engaging claw 15.

[0011] As described above, the fastening member of this embodiment has the band main body 1 wrapped around it in a ring shape, and one end of the fastening member. The portion 11 is inserted into the through hole of the fixing member 2, and both ends 11 are inserted with a jig. , 12, the first and second engaging claws 15 and 25 engage with each other. Because of this structure, the fastening work is easy and the workability is excellent. Moreover, after the fastening, the first and second engaging claws 15 and 25 are firmly engaged with each other. As a result, a secure fastening condition can be obtained without loosening the tightening force. I can do it.

0012 Note that the fastening member of this embodiment has six first engaging claws 15 arranged to achieve the following effects. Although it is designed to be able to handle fastened parts of different sizes, If the length is a certain size, one first engaging claw 15 is installed at a predetermined position on one end 11. It is also possible to just provide it. (Example 2) A plan view of the main parts of the fastening member according to this example is shown in FIG. The figure is shown in Fig. 7, and the plan view of the fixed member portion after fastening is shown in Fig. 8. FIG. 9 shows a front view of the fixing member portion in the case.

[0013] In the fastening member of this embodiment, the band main body 3 and the fixing member 4 are integrated with one metal plate. Basically, it has the same structure as the first embodiment. The band body 3 has a pair of locking parts 33, 33 at both ends 31, as in the first embodiment. , 32, and six first engaging claws 35 are provided at the end portion 31. It is.

[0014] The fixing member 4 is made by bending a single metal plate continuous with the other end 32 of the band main body 3. By doing so, a through hole through which one end portion 31 of the band main body 3 can be inserted is formed inside. It is formed into a rectangular cylindrical shape, and rises from one end of the outer wall toward the one end 31 side. It has a second engagement claw 45 that is raised inward so as to be inclined. in this case, As shown in a developed view in FIG. 7, the portions constituting the fixing member 4 are It is vertically symmetrically divided into two parts and formed into a predetermined shape, and along the chain line in Fig. 7. By bending, the outer wall 43 and the third Two engaging claws 45 are formed. The outer wall 43 and the second engaging claw 45 face each other at the center. The side surfaces are joined and fixed together by welding or the like.

[0015] The fastening member of this embodiment configured as described above connects the boot to the constant velocity joint body. When attached to the holder, it is fastened in the same manner as in the first embodiment. In this case, the When both ends 31 and 32 of the main body 3 are pulled together by a predetermined amount in the circumferential direction with a jig, the result shown in FIG. As shown in FIG. 9, the first and second engaging claws 35 and 45 engage with each other, The same actions and effects as in case 1 are achieved.

[0016] Furthermore, the fastening member of this example is manufactured by processing a single metal plate. Because of this, it has the advantage of being easy to manufacture and reducing manufacturing costs. Ru.

[0017]

[Effect of the idea]

According to the band type fastening member of the present invention, when fastening, one end is attached to the fixing member. Wrap the band body in a ring shape while it is inserted into the through hole of the first engaging claw and Fastening work by pulling both ends together with a jig until the second engaging claws engage each other. Because it is configured to complete the following steps, installation workability can be greatly improved. can.
