Motor driven throttle control device and method of mounting motor thereto

摘要

Provided is a throttle control device having a throttle body ( 1 ) forming an intake passage ( 1 a) inside the throttle body. A throttle valve ( 2 ) is rotatably arranged in the intake passage. A motor ( 4 ) rotates the throttle valve. The motor has a motor casing ( 28 ), which has one axial end portion and the other axial end portion. A first support device ( 5, 29 ) fixedly supports one axial end portion of the motor casing with respect to the throttle body. A second support device ( 6, 24 ) supports the other axial end portion of the motor casing with respect to the throttle body resiliently in the radial direction of the motor. The second support device includes a substantially ring-shaped resilient support member ( 6 ).
