ストッパとしての機能を兼備えている。The sealing material 4 has a side peripheral shape formed by an arcuate inner surface 41 that matches the recess 14 of the outer joint member 1 and an arcuate outer surface 43 that matches the inner peripheral surface 32 of the boot 3. Both ends of the outer joint member 1 in the axial direction are formed into a flat shape. The sealing material 4 is made of hard rubber that is harder than the boot 3, and has a material hardness that is approximately intermediate between that of the boot 3 and the outer joint member 1. Therefore, the annular stopper 33 is tightened by force, and the adhesion between the boot 3 and the sealing material 4 and between the sealing material 4 and the outer joint member 1 is good. This sealing material 4 is attached to each recess 14 of the outer joint member 1 and to the boot 3.
and the inner circumferential surface of each. Adjacent sealing materials 4 are connected by a tension spring 5 and pulled together. The tension spring 5 includes a linear main body 50 and an L-shaped spring part 52 extending perpendicularly from both ends of the main body 50. ing. The main body portion 50 of the bow tension spring 5 is located at a position crossing the open end of the spherical guide groove 12 formed on the inner periphery of the outer joint member 1, and prevents the roller member 27 from being pulled out from the spherical guide groove 12. It also functions as a stopper.

The inside of the space covered by is filled. However, in the fixing portion between the boot 3 and the outer joint member 1 that is opened in this embodiment, a sealing material 4 is interposed in each recess 14 of the outer joint member 1, and one end surface 3] of the boot 3 is fixed in the circumferential direction. Since it is formed into a cylindrical shape with a substantially constant wall thickness, the annular stopper 33
When tightening, the force is evened out. Therefore, the tightness at the fixed portion between the boot 3 and the outer joint member 1 is high, and leakage of lubricating oil can be prevented.
