<P>PROBLEM TO BE SOLVED: To reduce the weight of a motor unit while securing strength for the deformation of a base plate. <P>SOLUTION: A motor mounting board for the motor unit comprises the base plate 3 in which a mounting hole 32 that is used for mounting a motor to a prescribed position is formed and to which a part of the motor is fixed and a current supplying circuit that is provided on the based plate 3 and supplies a driving current to the motor. In addition to the mounting hole 32, openings 34 that contribute to the reduction of weight are formed on the base plate 3. Ribs 36 are formed that project from the back side of the base plate 3 along edges of the openings 34 of at least a part of peripheries of the openings 34. These ribs can secure the strength for the deformation of the base plate 3 on which the openings 34 that contribute to the weight reduction are formed, and thereby to reduce the weight of the motor unit or the motor mounting board. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
