摘要： PROBLEM TO BE SOLVED: To provide a structure for fixing a fixed portion of a dust cover in which a reinforcing ring is embedded, to a mounting member such as a socket, while improving fixing force. SOLUTION: The reinforcing ring 21 has an engaging protrusion 24 formed on part of the circumference by protruding part of the inner periphery from the inner peripheral face of the fixed portion 12 inward in the radial direction, and the mounting member 2 has an engaging groove 6 formed in part of the circumference for inserting the engaging protrusion 24. The engaging groove 6 serially has an one-end opening portion 7 as an insertion port for the engaging protrusion 24, a first groove portion 8 extending from the one-end opening portion 7 in one axial direction, a second groove portion 9 extending from the first groove portion 8 in one circumferential direction, and a third groove portion 10 extending from the second groove portion 9 in the other axial direction in a terminated shape. The engaging protrusion 24 is inserted from the one-end opening portion 7 into the first groove portion 8 and consequently into the second groove portion 9 during mounting, to engage with the third groove portion 10 with spring-back due to the rubber elasticity of the dust cover fixed portion 12.
