Description of the Related Art A constant velocity universal joint is used for transmitting power in an automobile or a motorcycle, and connects a drive shaft and a driven shaft so that the rotary power is kept at a constant speed even when they form a predetermined angle. It is configured for communication.
Further, in order to prevent dust and the like from entering the inside of the constant velocity universal joint, it is common to cover the space between the drive shaft and the constant velocity universal joint with a boot integrally formed of a rubber material or a resin material. Is. FIG. 4 shows a conventional example applied to a cross groove joint. The boot 21 includes a bent portion 2 between a large diameter portion 23 fixed to a cylindrical boot adapter 22 and a small diameter portion 24 fixed to a drive shaft (for example, shaft) S.
5 is formed. The small diameter portion 24 of the boot 21 is fastened to the groove portion Sa of the shaft S by the band 12, and the flange portion 22a of the boot adapter 22 is bolted to the outer ring H via the rubber packing 26.

In order to prevent grease and the like from leaking between the boot adapters 22 and 32 and the outer ring H of the constant velocity universal joint J, the rubber packing 26 or the O ring 34 must be interposed between the two. Further, the work of bolting the boot adapter 22 to the outer ring H or caulking the annular groove 33b requires not only dedicated equipment and tools but also a proper number of workers. Further, the development of a device for automatically assembling the boots 21, 31 and the like to the constant velocity universal joint J is not appropriate in terms of cost because the equipment becomes large-scale.
