Abstract
A power transmission device for converting rotational movement of a rotation shaft into reciprocal movement in an axial direction of the rotation shaft. This device comprises a bevel gear for converting rotation of the rotation shaft into rotational movement of a-second rotation shaft, a-first eccentric shaft turnable with an eccentricity to the second rotation shaft, a-second eccentric shaft turnable with an eccentricity of 180.degree. apart from the first eccentric shaft, a-first reciprocating member reciprocally movable in the axial direction only of the rotation shaft in response to the rotational movement of the second eccentric shaft, and a-second reciprocating member reciprocally movable in the axial direction only of the rotation shaft in response to the rotational movement of the first eccentric shaft. The second reciprocating member exerts a damping effect on the first reciprocating member.
