PROBLEM TO BE SOLVED: To provide a decelerator device for a construction machine capable of automatically reducing rotational speed of an engine down to an idling condition when an operator leaves the construction machine. SOLUTION: A main body frame 1 is provided with a main lever 2 connected with a throttle lever 9 of the construction machine through a first pull cable 10 and an auxiliary lever 4 connected with a control lever 11 of the engine through a second pull cable 12. This decelerator device is provided with a decelerator motor 8 switching the auxiliary lever 4 into a state for turning the auxiliary lever 4 in synchronization with the main lever 2 or a state for returning the auxiliary lever 4 to an initial position irrespective of position of the main lever 2. A bounding detection switch 16 is provided in an operation box 15. When bounding operation of the operation box 15 is detected by the bounding detection switch 16, current is carried into the decelerator motor 8, and the auxiliary lever 4 is returned to a position where engine speed is reduced down to the idling condition.
