The hydraulic fluid supply source mechanism includes a pump and a reservoir tank. The hydraulic fluid supply source mechanism further includes an unload line connecting a discharging port of the pump to the reservoir tank and an unload valve disposed in the unload line. The unload valve has an electromagnetic proportional valve and is controlled such that the current to be supplied thereto gradually increases and decreases when the valve is opened and closed, respectively.
