PROBLEM TO BE SOLVED: To provide a cushion with excellent mountability and hardly coming off once mounted. SOLUTION: The cushion comprises a body part 1 to play a role as a stopper and an engagement part 2 which is integrated with a bottom surface part 11 of the body part 1 via a connection part 3 contributing to the fitting to a fitting member 9, and these components are integrally formed of a rubber-like elastic body. The connection part 3 is rectangular in transverse section. Thick-walled parts formed between groove bottom parts of those facing each other among open-ended grooves 21 formed in the engagement part 2 are formed thin, and thin film parts 22 are disposed orthogonal to both side parts of the connection part 3 having a plate-like cross section. The length in the longitudinal direction of the open-ended grooves 21 is defined as the distance at which the diameter in the transverse sectional part of an introduction part 29 to form the engagement part 2 is equal to the outside diameter of a fitting part 25.
