<p>PROBLEM TO BE SOLVED: To provide a damper for paper conveyance part of a copier being compact and capable of preventing the generation of impact sound. SOLUTION: A shearing pin 26 is connected with a wall part of a cover 22, and a viscous body 28 is poured into a third hole of the cover 22. Next, a second shaft part is inserted into the third hole of the cover 22 through an O ring 30, and a shaft part of the shearing pin 26 is inserted into a shearing pin insertion hole of a shaftlike member 24. Consequently, the viscous body 28 is sealed in a first annular clearance 32 between an outer peripheral face of the second shaft part and an inner peripheral face of the third hole, the viscous body 28 is sealed in a second clearance 34 like an annular plate between a tip of the second shaft part and an inner face of the wall part, and the viscous body 28 is sealed in a third clearance 36 like a disc between a tip of the shaft part of the shearing pin 26 and a bottom face of the shearing pin insertion hole. The viscous body 28 is a silicone compound.</p> |
