- seal portion 42 has a plurality of seal lips 34, 47, and these seal lips 34, 47 are brought into pressure contact with the shaft portion 10 and the flange portion 13 of the ball shank 1, whereby the seal portion 42 and the ball shank are Sealing performance between 1 is enhanced and retained Leakage of the lubricant in the space 30 and external force are firmly prevented from entering the holding space 30.
- the flange portion 13 of the ball shank 1 is formed with a tapered surface 16 inclined with respect to the axial direction of the ball shank 1 on the outer peripheral side of the abutting surface 14, and the seal portion 32
- a side lip portion 48 projecting on the taper surface 16 covers the tapered surface 16.
- the side lip portion 48 is provided in the vicinity of the corner portion on the outer peripheral side of the seal portion 42, and protrudes so as to be obliquely expanded outward in the radial direction from the seal portion 42.
- the flange portion 1 3 In close contact with the tapered surface 16.
- the seal portion 42 exerts a contracting force to tighten the shaft portion 10 of the ball shank 1, and is pressed against the abutting surface 14 of the flange portion 13 along the axial direction of the ball shank 1. Therefore, the side lip portion 48 is pressed against the tapered surface 16 of the flange portion 13 by the resultant force of these forces. That is, the side lip portion 48 is in pressure contact with the tapered surface 16 inclined with respect to the axial direction of the ball shank 1 substantially from the front side. As a result, the side lip portion 48 and the tapered surface 16 of the flange portion 13 are in intimate contact with each other, and a seal lip is formed outside the end surface lip portion 47 to eliminate the entry of dust. The sealing performance between the part 42 and the ball shank 1 is improved.
- the force force that presses the side lip portion 48 against the tapered surface 16 of the flange portion 13 is generated as a resultant force of the contraction force in the radial direction of the seal portion 42 and the urging force in the axial direction. Even if the seal shank 1 oscillates and the seal main body 43 shifts to the bent state force advance state, it is possible to suppress a decrease in the pressure contact force of the side lip portion 48 against the flange portion 13, and the side lip portion 48 and the flange portion. It is possible to maintain the sealing state between the 13 tapered surfaces 16. Accordingly, it is possible to prevent as much as possible that the sealing performance between the ball shank 1 and the boot seal 4 is impaired as the ball shank 1 swings.
