A seal member has a ring shape which is assembled in a portion between a tubular member to be inserted into and fixed to a mount hole formed to a head cover of an internal combustion engine and a peripheral wall portion of the mount hole. The seal member is provided with an axial-direction seal portion formed to axial one end portion of the seal member, and a diameter-direction seal portion formed to another one end of the seal member. A fixing member configured to fix movement in a diameter direction of the seal member between the axial-direction seal portion and the diameter-direction thereof is formed along a peripheral wall portion of the mount hole. |
