<p>PURPOSE:To prevent a motor from rotating due to its own weight by a construction wherein a motor is supported at the front and rear thereof by each one fulcrum pin arranged at either of positions opposite to each other transversely of the motor axis, so that a straight line connecting between the fulcrums passes the center of gravity of the motor. CONSTITUTION:There are provided a motor 5 and a motor supporting member 6 for rotatably supporting the motor 5 through fulcrum pins 35, 61 each arranged at either of the front and rear of the motor 5. Each of the fulcrum pins 35, 61 is projected from the supporting member 6 in substantially parallel to the motor axis and also arranged at either of positions opposite to each other transversely of the motor axis, so that a straight line connecting between the fulcrums of the fulcrum pins 35, 61, through which the motor 5 is supported on the motor supporting member 6, passes substantially the center of gravity of the motor. By so doing, it becomes possible to prevent the motor from rotating about those fulcrum pins due to its own weight.</p> |
