摘要

The subject innovation is the front end in that, the muffler body 10. The exhaust pipe 20 distal end and is bent obliquely at a predetermined angle outward with respect to the normal, the bent exhaust pipe 20 of the extending of the rainwater inflow preventing silencer for construction equipment has been provided with a large expansion tube 22 than the diameter of the exhaust pipe 20, the line between the expansion tube 22, the distal end border (22a) on a hand that is cut in the radial direction, the expansion tube 22 of the depending rainwater drainage recess (22b) has a structure is formed, the expansion tube 22, rain water flowing into the inflow of rain water into the interior of the silencer body 10, thereby flows along the bottom wall surface escape the cutting gap (22b) the one will be completely blocked.
