PROBLEM TO BE SOLVED: To provide a sealing device which reduces the number of seal parts, expands dimensional accuracy and assembling accuracy of counterparts for mounting, thereby is advantageous in cost and is capable of realizing space saving in seal space. SOLUTION: This gasket is provided with a cylindrical reinforcing member 1 fitted into the inside of a first case member 51, one end side seal part 3 which is held by the reinforcing member 1, projects in the axial direction from the reinforcing member 1 and is very close to a second case member 52 and an other end side seal part 6 which is held by the reinforcing member 1, projects in the axial direction from the reinforcing member 1 and is very close to a third case member 53. The axial direction length of the one end side seal part 3 is set to a size which is more than twice as much as dimensional dispersion between the second and third members 52, 53, the axial direction length of the other end side seal part 6 is set to a length smaller than the axial direction length of the one end side seal part 3, and the other end side seal part 6 is arranged in the inside of the reinforcing member 1. |
