초록

A soundproof cover (30) is equipped with: multiple unit soundproof covers (31R, 31L) forming a portion of the circumferential cross section (30s); and connecting parts (35) provided on the periphery of the circumferential cross section (30s), and connecting the multiple unit soundproof covers (31R, 31L) in a detachable manner. The multiple unit soundproof covers (31R, 31L) are configured so as to be capable of being attached and detached with respect to a muffler (20) by moving the unit covers in a direction (the radial direction (R)) orthogonal to the a...
