ABSTRACT:
A throttle control device has a throttle body (TB) in which an intake passage (1a) is formed. A throttle valve (2) is rotatably arranged within the intake passage. A motor (4) rotates the throttle valve. The throttle body has a gear accommodating chamber (19), in which is arranged gear mechanism (35). The gear mechanism transmits the rotation of the motor to the throttle valve, and has at least one gear (14). A shaft (34; 134) rotatably supports the gear. The shaft is a unitary member formed integrally on a wall surface (1b, 18b) of the gear accommodating chamber in a cantilever fashion. The shaft may have first shaft portion (34a) formed integrally on first wall surface (1b) of the gear accommodating chamber in a cantilever fashion and second shaft portion (34b) formed integrally on a second wall surface (18a) of the gear accommodating chamber in a cantilever fashion.
