Claims

[Scope of utility model registration request]

A DC motor, a hydraulic pump driven by the DC motor, a pair of cylinder ports, and a pair of cylinder ports that are locked in a neutral position, and one of which is turned into a discharge port when the cylinder port is switched from the neutral position to a switching position by tilting a lever. and a manual 4-port 3-position switching valve, the other end of which is connected to the tank port, and a limit switch is provided in the operating electric circuit of the DC motor, and the limit switch and the lever are A compact hydraulic power source featuring a contact switching mechanism that switches the limit switch to close by tilting.
