Control device of clutch operation shaft for converting 2 wheel/4 wheel driving vehicle

A device for controlling a clutch operation shaft for converting 2wheel/4wheel of a vehicle is provided to reduce an installation cost and to use a general motor as an operation source of the clutch by controlling the clutch operation shaft using a simple solenoid. A device for controlling a clutch operation shaft(11) for converting 2wheel/4wheel of a vehicle comprises a lower plate(21), a case(22), a magnetic upper plate(23), an elastic member(24), and an electromagnet(25). The lower plate is engaged with an outer periphery surface of the clutch operation shaft, and rotates with the clutch operation shaft. The lower plate is placed in the case. A boss unit(22a) of the case is formed at the outer periphery surface of the clutch operation shaft, and rotates. The magnetic upper plate is formed at the outer periphery surface of the clutch operation shaft, and linearly moves to axis direction by a linear motion guide unit. The magnetic upper plate adheres to the lower plate selectively, and moves between connection location and disconnection location where separated from the lower plate. The elastic member is installed in the case, and gives elasticity to the upper plate to be located on the connection location. The electromagnet is installed in the case, and generates a greater magnetic force than elasticity of the elastic member to move the upper plate to the disconnection location.
