Beschreibung
Zusammenfassung:	A variable pitch device includes a body, a drive unit fixed to the body, a plurality of movable fingers disposed movably along a longitudinal direction of the body, and a driving force transmission mechanism that transmits a driving force of the drive unit to the movable fingers. The driving force transmission mechanism is formed of a connecting block connected to an end block driven in a vertical direction, a cam plate accommodated in the body and connected to the connecting block, and four finger pins inserted through first to fourth cam grooves of the cam plate. The finger pins are disposed movably in the longitudinal direction along guide holes of the body and connected to the movable fingers.
