An accelerator for a carburetor that is linked to a throttle valve and allows a piston-type accelerator pump to be operated in a simple configuration that dispenses with a link mechanism and does not greatly enlarge the carburetor. The lower surface of a throttle valve lever 10 is provided with a cam 33 that has a circular shape centered about a throttle valve stem 8 and is configured such that the cam surface 33A thereof faces a carburetor main body 1. An accelerator pump 25 is placed parallel to the throttle valve stem 8 and the upper end of a piston rod 28 thereof is brought into contact with the cam surface 33A. The cam 33 pushes the piston rod 28 down as the throttle valve lever 10 swings in the opening direction of the throttle valve, and the acceleration fuel in the pump chamber 29 is delivered and supplied to the suction channel 2.
