摘要： A throttle device 1 includes a throttle valve 2 which is disposed in an intake passage 101, and includes a first valve body 20 and a first rotatable shaft 21 for rotatably holding the first valve body 20, a bypass valve 3 which is disposed in a bypass passage 8 connected to the intake passage 101 so as to bypass the throttle valve 2, and includes a second valve body 30 and a second rotatable shaft 31 for rotatably holding the second valve body 30, a common motor 4 for applying a driving force to the throttle valve 2 and the bypass valve 3, a first gear 5 configured to be able to transmit or block the driving force of the motor 4 with respect to the first rotatable shaft 21, a second gear 6 configured to receive the driving force of the motor 4 and transmit the driving force to the second rotatable shaft 31, and a sensor 7 for detecting a rotation amount of the second rotatable shaft 31 of the bypass valve 3 or another rotatable shaft rotating in conjunction with the second rotatable shaft 31.
