Claims

[Scope of utility model registration request]

An electric motor that drives a hydraulic pump that sucks in and discharges oil and a hydraulic control valve that controls the flow of oil are placed on the top plate of a tank that stores oil inside.This tank has a roughly square bottom plate. a back plate part that stands up from the bottom plate part; a first side plate part that stands up from the bottom plate part and extends in a direction substantially orthogonal to the back board part; a second side plate part that extends substantially perpendicularly to the back plate part; a front plate part that stands up from the bottom plate part and faces the back plate part and extends substantially orthogonally to the first side plate part and the second side plate part; A back plate part that is formed in a sealed manner and has a top plate part that faces the bottom plate part and is continuous with the back plate part, the first side plate part, the second side plate part, and the front plate part in a substantially perpendicular direction, and forms a tank; The upper ends of the first side plate part and the second side plate part are respectively extended above the top of the electric motor and the hydraulic control valve to form an exterior cover that covers the electric motor and the hydraulic control valve from three directions. A hydraulic unit comprising a front opening facing a plate portion and an upper opening located above an electric motor and a hydraulic control valve, which are closed by a removable lid member, and an exterior cover provided with a mounting portion for an actuating device.
