Claims

[Scope of utility model registration request]

In a crank device comprising a crank arm that is rotated by a rotational drive shaft, and an interlocking rod for reciprocating drive that is pivotally connected to a pin provided at the tip of the crank arm on the rotation side, the rotation of the crank arm A threaded rod in the axial direction of the arm that is rotatably operated is provided at the side tip, the pin is screwed onto the threaded rod, and the pin is erected, and the movement is adjusted in the axial direction of the arm while being guided by a guide provided on the crank arm. What is claimed is: 1. A crank device comprising: a crank turning radius adjusting mechanism which prevents displacement of said movable member by a lock nut screwed onto said threaded rod;
