Fuel spray device

The invention provides a fuel spray device being capable of implementing miniaturization of the device and improving vibration resistance of vibrations relative to an engine. A fuel spray device (10) integrally includes a throttle body (12) having a tubular wall part (20) for forming an intake channel (21), a fuel spray valve (14) for spraying the fuel in the intake channel (21), a fuel pump (16)for supplying the fuel spray valve (14) with the fuel, and a fuel pressure adjusting valve (18) for adjusting pressure of the fuel supplied for the fuel spray valve (14). The fuel pump (16) and the tubular wall part (20) of the throttle body (12) are configured in parallel. The fuel pump (16) and the fuel pressure adjusting valve (18) are individually configured along a direction crossed with an arrangement direction of the fuel spray valve (14) and the tubular wall part (20) of the throttle body (12).
