Abstract: A holder of a surface mount motor includes a bottom-raising piece formed so as to extend integrally from the bottom portion and bent at a predetermined bending angle with respect to the bottom portion. When the holder is attached to a motor body, there is a risk that a mounting surface of the bottom portion of the holder will not be in the same plane as a mounting surface of a terminal. In such a case, a fine adjustment may be performed simply by slightly raising or lowering the bottom-raising piece. Thus, an adjustment between the heights of the mounting surface of the bottom portion of the holder and the mounting surface of the terminal can be easily performed. A gap between the bottom portion of the holder and the motor casing can be easily changed simply by changing the bending angle of the bottom-raising piece.
