ABSTRACT:
A driving device for reciprocating a shaft along an axial direction thereof, comprises a reciprocating shaft drum for slidably supporting the reciprocating shaft along the axial direction thereof, a guide groove drum rotated relative to the reciprocating shaft drum and having an annular guide groove with an intersection on the circumferential surface thereof, and a driven member fixed to the reciprocating shaft and engaged with the guide groove. The driven member includes a cam follower and a boat-shaped member rotatable about a shaft extending from the driven member to the guide groove, the boat-shaped member has a cam roller rotatable about another shaft extending from the driven member to the guide groove, and the guide groove has a cam follower guide path engaged with the cam follower, a cam roller guide path engaged with the cam roller and a boat-shaped member guide path engaged with the boat-shaped member at the intersection thereof. When the guide groove drum is rotated relative to the reciprocating shaft drum, the shaft is reciprocated by engagement of the driven member and the guide groove.
