Patent number: 7469879Abstract: A motor is properly aligned with a throttle valve and vibration resistance of the motor is improved. In a throttle device having a motor for driving a throttle valve, the motor is inserted into a motor casing provided in a throttle body. A portion on the output-shaft side of the motor is held in its radial direction in the vicinity of the motor-insertion opening of the motor casing. A portion opposite to the output-shaft side of the motor is provided with elastic pieces or elastic projections. The motor and the elastic pieces or elastic projections are formed in a single piece, or the elastic pieces or elastic projections are attached to the motor.
