<p>PROBLEM TO BE SOLVED: To provide a mounting structure for a dumper capable of assembling a dumper body provided with a thin rotation axis to an inner part by using an opening part formed with casings. SOLUTION: This mounting structure comprises a recessed groove part 16 continued from a casing opening part 13 formed on an inner surface 11a of a wall surface member 11, a positioning plate 23 provided at a dumper body side base part of a dumper thin axis part 22, an axis hole 14 being larger than a section of the dumper thin axis part 22 opening in the recessed groove part 16, and an axis securing part 31 having an outer periphery surface to be turnably inserted into a fitting hole 33 and the axis hole 14 provided in a lever 30 and connected with each other for transmitting torque by inserting the dumper thin axis part 22, and is composed such that the recessed groove part 16 has a larger shape than the positioning plate 23 to get into the recessed groove part 16 at an assembly position of a dumper body 20 while crossing with the recessed groove part 16 at a turning position of the dumper body 20 to perform positioning in the axial direction.</p> |
