To fix even an insertion member having the different outside diameter dimension, and to avoid application of an excessive load to the insertion member.
A hose supporting mechanism 15 is provided in a hole part 8a of a machine body frame 8 in a cab. In the hose supporting mechanism, a supporting member 18 having an insertion hole 17 through which a hydraulic hose 12 is inserted to be held is fitted to a recession 20a of a receiving part 20, and is fastened and fixed by a fitting part 21 and the receiving part 20. The supporting member 18 is composed of an elastic member such as natural rubber. The support member 18 compresses and deforms a ring-shaped rib 23 disposed on the inner wall center of the insertion holes 17, and fixes the hydraulic hose 12 having the different outside diameter dimension. A long groove continued to the insertion hole 17 is formed on a side surface of the supporting member 18, the long groove is widened and opened, and the hydraulic hose 12 is inserted into the insertion hole 17. The supporting member 18 is held between the receiving part 20 and the fitting part 21, and is elastically deformed by the long groove part, and the hydraulic hose is air-tightly pressure-fixed by the rib 23.
