Abstract: 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.

The rotation transmission mechanism (20) is disposed at a position where the first and the second throttle bodies (11f, 11s) are adjacent, the motor (15) is disposed within an installation width Ws of either one of the first and the second throttle bodies (11f, 11s), and the throttle opening degree sensor (30) is disposed within an installation width Wt of the other one of the first and the second throttle bodies (11f, 11s).

Abstract: A compact multiple throttle device where multiple throttle shafts are driven by a single drive force. A throttle device includes a first throttle shaft to which a first throttle body and a third throttle body are fixed and also includes a second throttle shaft to which a second throttle body and a fourth throttle body are fixed. The first throttle shaft and the second throttle shaft are parallel to each other. The third throttle body and the fourth throttle body are integrally coupled to each other in a gear case. In the inside of the gear case, a motor for driving the first throttle shaft and the second throttle shaft is arranged. Further, first to sixth gears for transmitting drive force of the motor to the first throttle shaft and the second throttle shaft are included.
