CONSTRUCTION MACHINE

摘要

A right front housing cover is arranged in the right side of a working mechanism, and a first control valve is arranged in a front portion side of a valve accommodation room that is covered with the right front housing cover. Further, a signal control valve block is arranged in the back side of the first control valve and in the upper side of the first control valve, and a solenoid valve is arranged in the back side of the signal control valve block. A front surface plate forming part of the right front housing cover has a lower side is inclined in an oblique downward direction toward the forward side, and is arranged along a virtual line that extends in an oblique downward direction through a front end portion of the first control valve and a front end portion of the signal control valve block.
