An electric hand with a torque limiter comprising:

• a pair of jaw members which can be opened and closed for grasping a workpiece;
• an electric motor having a rotating drive shaft;
• a converter mechanism provided between said drive shaft and said jaw members for converting a normal or reverse rotation motion of said drive shaft into an opening and closing motion of said pair of jaw members, said converter mechanism having a cam member which is normally or reversely rotated by said drive shaft, a pair of cam grooves formed in said cam member, and drive pins respectively mounted to the jaw members and fitted to the pair of cam grooves, said drive pins are displaced in said cam groove by a normal or reverse rotation of said cam member in an opening or closing direction of said jaw members;
• and
• a torque limiter provided between said drive shaft of said electric motor and said cam member of the converter mechanism for limiting a torque of said drive shaft transmitted to said cam member.
