Patent attributes
A throttle device, comprising: a throttle valve (13) disposed in a plurality of intake passages (12) of a throttle body (11); a throttle shaft (14) supporting the throttle valve (13); a motor (15) for driving the throttle valve (13) to open and close through the throttle shaft (14); a rotation transmission mechanism (20) interposed between the motor (15) and the throttle shaft (14); and a position sensor to detect a displacement in the rotation transmission mechanism (20). The rotation transmission mechanism (20) includes a pinion (21) driven by the motor (15) and a control gear (23) interlocked with the pinion (21) and integrally connected to the throttle shaft (14). The position sensor (30) to detect an angular displacement of the control gear (23) and the rotation transmission mechanism (20) are disposed between the plurality of intake passages 12.
