Provided is a hydraulic pump mounting structure configured so that, with the use of a simple structure having a reduced number of parts, the hydraulic pump mounting structure can effectively reduce the displacement of a hydraulic pump caused by the discharge pressure of hydraulic oil. A hydraulic pump mounting structure comprises: a mounting surface (31) for a hydraulic pump (1), the mounting surface (31) being provided on a transmission casing (30); a pump casing (10) for the hydraulic pump (1) mounted on the mounting surface (31); the discharge port (3) of the hydraulic pump (1), the discharge port (3) being formed protruding from the pump casing (10) and being disposed on a surface different from the mounting surface (31); a discharge opening (4) provided at the discharge port (3) and discharging hydraulic oil; a hydraulic pressure-subjected section (5) provided to the discharge port (3) and subjected to the pressure of hydraulic oil discharged from the discharge opening (4), the pressure acting in the direction opposite the direction toward the discharge opening (4) with both directions lying along the same axis; and a contact section (7c) provided to the hydraulic pressure-subjected section (5) and disposed so as to be capable of coming into contact with the contact receiving section (32c) of the transmission casing (30). |
