Claims

[Scope of utility model registration request]

In a crank handle device configured at an end of a drive shaft connected to a lifting mechanism for a floor such as a bed, the crank arm includes a fixed arm on the drive shaft side, and at least a fixed arm at the tip of the fixed arm. a movable arm provided so as to be freely bendable in an outward direction, and a grip is provided at the tip of the movable arm so that the movable arm is parallel to the drive shaft in an unbent state; Furthermore, the movable arm is bent outward of the fixed arm so as to cover the fixed arm together with the grip, and has a bent portion so as not to protrude outward in the covered state. A crank handle device for raising and lowering a floor part of a bed, etc.
