よる異音は殆んど発生しない。According to the first feature, a gap is formed between the side edge of the housing main body and the side plate by a notch, and the expansion and the expansion of the combustion housing are achieved.
Generation of abnormal noise due to friction between the side edge of the housing main body and the side plate during contraction is prevented. The shoulder abuts on the side plate, but the shoulder is located near the claw engaging with the slit hole in the side plate, so that the shoulder is almost displaced relative to the side plate even when the combustion housing expands or contracts. No noise is generated due to friction between the shoulder and the side plate.
