  • Publication number: 20210317793
    Abstract: A general engine throttle apparatus includes a throttle body 12, a throttle valve 13, a throttle shaft 14, a driven gear 24, an electrically driven motor 15, and a detected body block 26. The throttle valve 13 opens and closes an intake air introduction hole 11. The throttle shaft 14 holds the throttle valve 13 and is rotatably supported by a holding hole 16 of the throttle body 12. The electrically driven motor 15 transmits a rotation operation force to the driven gear 24. The detected body block 26 is attached to another end part in an axial direction of the throttle shaft 14, and a state of the throttle shaft 14 is detected by a sensor. The driven gear 24 is integrally formed on one end side in the axial direction of the throttle shaft 14. The detected body block 26 is formed to have a maximum outer diameter that is smaller than a minimum inner diameter of the holding hole 16.
