There is provided a load sensitive magnetic clutch device including: a magnetic pole rotating body 14 having magnetic poles 14a arranged on the circumference thereof and provided with a clutch projection 16 of a claw clutch at an end thereof; a yoke rotating body 12 configured to rotate about an axial center of rotation 18b identical to that of the magnetic pole rotating body 14, including a tooth-shaped portion arranged so that tooth tips face the magnetic poles 14a and provided with the magnetic pole rotating body 14 and a tooth-shaped magnetic body 12a configured to transmit a torque caused by a magnetic attracting force; and high-torque input means 2 configured to rotate about the identical axial center of rotation 18b and having a clutch engaging portion 3 engaging the clutch projection 16, wherein the clutch projection 16 is formed of a magnetic body, the clutch engaging portion 3 includes a clutch retaining magnetic body 4 configured to attract the clutch projection 16 by a magnetic force, and the clutch projection 16 is attracted by the clutch retaining magnetic body 4 by an application of a load torque exceeding a torque which is transferrable between the magnetic pole rotating body 14 and the yoke rotating body 12. Therefore, a function to prevent an occurrence of a clutch return in which the load torque applied to a clutch portion during a winching operation of a load in a load sensitive magnetic clutch in the related art is reduced by an action of a mechanical brake and a torque transmitting route is switched to a low-load transmitting route is achieved.
