A pallet lifting device and a power absorption device that can be interlocked with the ring gear are provided.

According to this structure of the present invention, the pallet supporting the internal combustion engine is carried above the bottom plate part with the movable upright plate part lying sideways. Then, with the pallet supported by the lifting device, the positioning knob pin is fitted into the upright plate side. At this time, the ring gear is in a state where it can be interlocked with the starting device and is also interlocked with the power absorption device. In this state, the movable upright plate is erected and pressed against the rear surface of the internal combustion engine with the pressing elastic body. This allows the internal combustion engine to be completely locked onto the support base. The lifting device is then operated downward to separate the pallet from the internal combustion engine. In this state, the test is started, and the internal combustion engine can be started by activating the starter, and the no-load operation is continued. At this time, the vibration of the internal combustion engine can be absorbed by the anti-vibration rubber. Then, the rotational force of the internal combustion engine can be transmitted to the power absorption device side and the load operation can be started.

An embodiment of the present invention will be described below based on the drawings.
