The inside of the noise absorbing spaces includes wall surfaces(21a) and at least one projection(21b). Combining units are formed at two ends of the front panel. Projections are formed at one side of the combining units, and combining grooves are formed at the other side thereof. The combining units include a pipe(40), and a clamp assembly(50). The clamp assembly includes a body, hook members(52), a spring, a bolt(54), and a catching protrusion(19).
