Abstract
A disclosure is made of an electric motor assembly in which a motor casing containing a motor and a battery casing housing one or more batteries are coupled in a manner so that a motor energizing circuit is turned on or off by relative rotational displacement between said two casings and the motor is fixed within said motor case by means of a terminal or contact strip. Further disclosed are raised ridges or grooves provided on said battery casing as means of supporting the whole assembly of said electric driving device, a method of immovably fixing said battery casing where said motor casing is made free for rotational displacement, a method of facilitating rotational displacement of said battery casing where said motor casing is immovably fixed, and also a switching mechanism.
