摘要： PROBLEM TO BE SOLVED: To secure ventilation performance for restraining excessive deformation of boots, without impairing the seal action of the boots. SOLUTION: An air vent H for communicating the joint inside and outside is arranged at an angle in the shaft direction in a fitting part of the boots 51 and a shaft 22. The air vent H can be formed longer in a length range in the predetermined shaft direction of the fitting part. When lengthening the air vent H, sealing property for restraining intrusion of foreign matter and leakage of a lubricant is provided. Since the sealing property is imparted to the air vent H itself for securing ventilation performance, the service life of the boots 51 can be lengthened without impairing the seal action of the boots 51 by the breathing action by the air vent H.
