PROBLEM TO BE SOLVED: To provide the fitting structure of an L-shaped channel joint to have the degree of selection freedom for positioning to the circumferential direction of the discharge side pipe part of the L-shaped channel joint and control the loosening of a screw member which screws the L-shaped channel joint to a base member through a fitting plate. SOLUTION: An inflow pipe part (1d) of the L-shaped channel joint (1) is inserted and arranged into the channel hole (3b) of the base member (3). While arranging a fitting plate (10) on the end face (3c) of the base member (3), a fitting hole (10d) is arranged at the fitting project part (1h) of the L-shaped channel joint (1) and the fitting plate (10) is screwed to the base member (3) by the screw member. The screw member is formed of a bolt head part (11a), a large diameter part (11b) and a thread part (11c), and an axial length (b) of the large diameter part (11b) is formed same as that of the plate thickness (a) of the fitting plate (10) or largely.
