PURPOSE: To prevent a muffler from play due to a gap between the muffler and a cylinder head by forcing a communicating pipe through a hole in the muffler into an intake port of the cylinder head to attach an elastic body to the outer periphery of the communicating pipe between said pipe and the cylinder head.
CONSTITUTION: In the beginning of running a compression element 3, a cylinder head 7 is given high temperature by discharge gas to expand a communicating pipe 16 together with a main body 14. A force, however, is produced in the direction of pulling out the communicating pipe 16 by the expansion of the main body 14 due to the difference of coefficient of linear expansion. When said pipe 16 is forced into the main body to minimize an elastic body 19, it is pulled out against the press-in force by an amount corresponding to the expansion of said body 19. Also, when the communicating pipe 16 is pressed in so as to leave slight elasticity of said body 19, the expansion of said body 14 contracts the elastic body 19 so that the communicating pipe 16 is not pulled out. The temperature of the head 7 is varied with the intermittent running while the expansion of the main body 14 is absorbed by the elastic body 19 without producing any play of the main body 14.
