<p>Disclosed is a steering hydraulic pressure generation unit (6) which is a power steering device for a small-size ship, this power steering device being such that on a common base (28), there are placed, in parallel, an electric assist device (26) and a helm pump (27) which is a swash plate type axial piston pump, and that beneath the common base (28), the electric assist device (26) and the helm pump (27) are integrally connected together by a transmission mechanism (34). The electric assist device (26) is supported by an instrument panel (3). Since the electric assist device (26) and the helm pump (27) are placed in parallel, the vertical length of the hydraulic pressure generation unit (6) can be reduced. As a result, the distance between the instrument panel (3) and the ship bottom (2) can be reduced, the position of the steering wheel can be lowered, and the position of the navigator's seat can also be lowered. Consequently, the lowering of the center of gravity is achieved.</p> |
