PURPOSE:To make the dimentional error of a fitted unit negligible, by a method wherein the salient section of a drain tube which is more flexible than a connecting member is provided between the salient section of the connecting member and the fitted unit. CONSTITUTION:A salient section 3a is formed on the inner peripheral side of the end frame 2 side end section of a drain tube 3,and the wideth of the salient section 3a is arranged to be slightly larger than a space between the end frame 2 and a sub-salient section 4c. the inner periphery of the salient section 3a is butt-jointed to the outer periphery of the cylinder section 4a of a connecting member 4. The sub-salent section 4c of the connecting member 4 is inserted into the groove 3b of the drain tube 3, and the salient section 3a is inserted between the sub-salient section 4c and the end frame 2, and the tube 3 is fixed in the drain hole 2a of the end frame 2 to be press-jointed. Accordingly, the dimensional error of a fitted unit can be made negligible due t the salient section 3a. |
