To provide an accelerator cable device capable of preventing the sudden operation of a throttle lever by smoothly transmitting operation from an accelerator pedal to the throttle lever of a throttle valve.

This accelerator cable device for transmitting the stepped state of the accelerator pedal to the throttle valve of an engine is constituted by connecting a buffer means for smoothly transmitting operation from the accelerator pedal to the throttle lever of the throttle valve, between an outer casing through which an inner cable is inserted, and a cable support part mounted to an accelerator cable guide.
