Abstract
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. The elastic pieces or elastic projections are deformed inwardly of the radial direction of the motor so that the portion opposite to the output-shaft side of the motor is supported in its radial direction in the motor casing.
