Abstract (en)

A throttle apparatus (60) includes: a throttle valve (66) disposed in an intake air passage (61) of an engine (3), a throttle shaft (65) connected to the throttle valve (66) and rotatable in a predetermined operational angle range, a motor (71) for rotating the throttle shaft (65), and a reduction mechanism (72) for transmitting, to the throttle shaft (65), the rotation of the motor (71) as reduced in rotational speed. The reduction mechanism (72) has a plurality of gears (76,77,78) including a first gear (77) rotatable in a rotational angle range greater than the operational angle range of the throttle shaft (65) and smaller than 360 degrees. The throttle apparatus (60) further includes a rotational angle sensor (82, 91, 92) for detecting the rotational angle of the first gear (77).
