PURPOSE: To make it possible to drive a device with a single driving source by providing a cam for reciprocating operation and a cam for vertical operation, and reciprocating and vertically moving the device while driving a link mechanism with said cam, in a mechanism where a transfer bar makes both vertical and reciprocating motion.

CONSTITUTION: By driving and turning a cam shaft 15 to turn the second cam 41 and by displacing a roller 44 in contact with the cam 41, a transfer bar 3 is lifted via an arm 46 and a guide groove 30. Simultaneously, a rod 35 moves via the arm 46, and thereby another lever 32 is rocked, a transfer bar 3 is lifted, and a pin 4 is fitted in the pin hole 7 of a work A to remove a pin 5 from a pin hole 6 while lifting 7-7A from a conveyor bench 2. Further, when the cam shaft 15 is turned, a roller 14 rocks taking a shaft 10 as an axis of rotation while following a cam 16, allowing the transfer bar 3 to be reciprocated.
