Muffler draining apparatus for working machine

摘要

A muffler draining apparatus for a working machine is provided which allows a drain line having excellent heat resistance to be reliably installed, even when a device or equipment is present at the position below a muffler. In a muffler draining apparatus that is provided to a muffler (12) equipped to a hydraulic excavator, and includes a drain line that discharges water accumulated in the muffler (12) to the outside of a vehicle body, the above-described drain line includes a single metal tubing (23) whose one end (23a) is connected to the muffler (12), and whose intermediate portion (23c) provided continuous to the one end (23a) is extended into the space formed between the muffler (12) and a hydraulic pump (11) located below the muffler (12). The intermediate portion (23c) of the metal tubing (23) includes a single linear portion (23c1) and plural bent portions (23c2). Also, the muffler draining apparatus includes, for example, a single support bracket (20) that is fixed to the muffler (12), and supports the intermediate portion (23c) of the metal tubing (23).
