Throttle valve control device

A throttle valve control device comprising a throttle body having an intake passage,

• the throttle valve control device driving a throttle valve for controlling an intake air flow rate or a pressure, disposed in the intake passage, with a motor via a throttle gear, and
• the throttle valve control device being attached externally with a bolt inserted into an attachment hole formed in the throttle body, wherein
• only three attachment holes are formed in the throttle body,
• one attachment hole among the three attachment holes is formed closer to a center of gravity of the throttle valve control device than the other two attachment holes,
• the one attachment hole is formed between the motor and a throttle shaft,
• the center of gravity is located separate from and immediately adjacent to a portion of the throttle body that defines the one attachment hole, and the other two attachment holes are formed on a side that is distal from the center of gravity.
