ABSTRACT:
A throttle control device includes a throttle body (1). In the throttle body, an intake passage (1a), a first space (24a), and a second space (44) are formed. In the intake passage, a throttle valve (2) is rotatably arranged. The throttle valve is rotated by a motor (4). The motor is accommodated in the first space. The second space communicates with the first space. In addition, the second space is adjacent to the intake passage through the intermediation of a wall portion (20a). This makes it possible for the heat generated in the motor to be effectively dissipated from the first space into the intake passage via the second space and the wall portion.
