Abstract (en)
A throttle device 10 includes: a throttle body 20 having a bore 12 opening to a first end surface 21 and a second end surface 22; a throttle shaft 40 disposed rotatably within the bore 12; and a throttle valve 50 fixed to the throttle shaft 40 so as to be located at least partially within the bore 12. The bore 12 has an inner surface defining an intake flow path 13 that decreases in flow-path cross-sectional area at least partially from a first open end 14 to a second open end 16 of the bore. The inner surface of the bore 12 has: a pair of through holes 18 through which the throttle shaft 40 passes; and a pair of grooves 24 that run from each of the through holes 18 to an edge of the second open end 16.
