Leicht an einem Rahmen zu befestigende Motorvorrichtung

摘要

In a motor device (38) having a motor (42), a reduction mechanism and a housing (44) with an installation leg (40) integrally formed therewith by a pair of dies (50) parting in an axial direction of an output shaft of the reduction mechanism, the installation leg is composed of a side surface (46) coming in surface contact with a frame, a first recess portion (56) for holding a nut whose entire inner surface is opened at least on one side of the housing in a die parting direction of the dies and a second recess portion (64) for inserting a bolt whose entire inner surface is opened on the other side of the housing in the die parting direction of the dies and which extends from the side surface to the first recess portion nearly perpendicularly to the axial direction of the output shaft. By inserting the bolt into the second recess portion through an installation hole (36) of the frame and screwing a bolt (62) into a nut (54) housed in the first recess portion, the housing is fixed to the frame.
