Clutch-equipped motor and electric chain block

A clutch-equipped motor for transmitting a driving force to a drive transmission shaft, the clutch-equipped motor comprising:

• a stator configured to generate a rotating magnetic field by passing a current through a coil;
• a rotor in an inner cylindrical portion of the stator and rotatable by the rotating magnetic field;
• a motor shaft through a center in a radial direction of the rotor and configured to rotate with respect to the rotor via a bearing;
• and
• a friction clutch mechanism on an end portion side of the rotor in an axial direction of the motor shaft, wherein
• the friction clutch mechanism has:
• a clutch plate fixed to an end surface side of the rotor in the axial direction of the motor shaft and configured to rotate integrally with the rotor;
• a connection member having a cylindrical part, the motor shaft and the drive transmission shaft being in an inner cylindrical portion of the cylindrical part of the connection member so as be rotatable integrally and synchronously with the cylindrical part;
• a clutch receiver on an outer peripheral side of the connection member and configured to rotate integrally with the connection member;
• and
• a biasing member configured to bias the clutch plate and the clutch receiver in a direction of bringing the clutch plate and the clutch receiver into contact with each other.
