WORKING MACHINE

A working machine includes a machine body; a tank including a tank body (131) to store a liquid, and a tubular portion (132) protruding from an outer surface (131a) of the tank body (131) in a protruding direction inclined from the outer surface (131a); a fixing piece having a through hole through which the tubular portion (132) is inserted, to fix the tank to the machine body; and an elastic member (145) sandwiched between the fixing piece and the tubular portion (132). The tubular portion (132) has one end connected to the tank body (131) and another end defining a liquid supply opening (135). The elastic member (145) is fitted on the tubular portion (132) substantially in parallel to the outer surface (131a) and non-perpendicularly to the protruding direction. The fixing piece (133) is fitted on the elastic member (145) fitted on the tubular portion (132), substantially in parallel to the outer surface (131a), and is fixed to the machine body.
