Claims

[Scope of utility model registration request]

In a reciprocating drive device comprising a worm attached to the shaft end of a reciprocating roller of a rotary printing press, a worm wheel meshing with the worm, and a shaft fixed to the worm wheel and having an eccentric shaft portion, the eccentric shaft an eccentric bush rotatably fitted in the large diameter portion of the eccentric bushing, a bush rotatably fitted inside the large diameter portion of the eccentric bushing and fixed to the eccentric shaft portion; a plurality of radial holes, a radial screw hole provided in a large diameter portion of the eccentric bushing, and a lock bolt inserted into the radial hole of the bush and screwed into the screw hole of the bush. A reciprocating drive device for a reciprocating roller, characterized in that the stroke of the reciprocating roller is changed by adjusting the relative angle between the eccentric bushing and the bushing using the lock bolt.
