Claims

[Claims for Utility Model Registration] (1) It has an elastic body whose one end is fixed to the drive shaft of the constant velocity joint, and a metal cylindrical body whose one end is fixed to the outer ring of the constant velocity joint. In a flexible boot for a constant velocity joint whose end is fitted and fixed inside the other end of a metal cylinder,
The metal cylindrical body is provided with an inclined portion that extends from near the other end of the metal cylindrical body so as to gradually increase in diameter toward the one end of the metal cylindrical body, and the constant velocity joint is actuated. A flexible boot for a constant-velocity joint, characterized in that the grease contained in the inner space of the flexible boot is made to flow toward the joint body. (2) In the flexible boot for a constant velocity joint according to claim 1, substantially the entire portion between the other end of the metal cylindrical body and the one end of the metal cylindrical body is in the inclined part. Flexible boots for constant-velocity joints that feature a curved shape. (3) In the flexible boot for a constant velocity joint according to claim 1, the inclined portion extends from near the other end of the metal cylindrical body to a position slightly before the one end of the metal cylindrical body. The metal cylinder has an annular recess for retaining grease that is located between the one end of the metal cylinder and the slope and has a diameter larger than that of the slope. Flexible boots for constant velocity joints featuring:
