A suction unit provided with a suction mechanism for attracting a workpiece at one end of a shaft attached in a body, said suction unit comprising:
- a rotary driving source which is provided with said body and which is driven by an electric signal;
- a rotary member which is connected to a rotary shaft of said rotary driving source and which is rotated integrally with said rotary shaft;
- a connecting rod which has one end rotatably supported on a portion of said rotary member offset from a center of rotation of said rotary member;
- and
- a connecting member on which the other end of said connecting rod spaced by a predetermined distance from said one end of said connecting rod in an axial direction is rotatably supported and which is connected to a shaft inserted into said body,
- wherein said rotary member is rotated by said rotary driving source, and said shaft reciprocates along said axial direction by said connecting rod.
