HYDRAULIC OIL TANK FOR CONSTRUCTION MACHINE
To provide a hydraulic oil tank capable of assuring strength at a gage installation part and bringing a gage close to a hole portion of an exterior cover while maintaining a predetermined clearance between the exterior cover and the hydraulic oil tank. A hydraulic oil tank (6) is mounted on a swing frame (2a) of an upperstructure (2) in a hydraulic excavator, has a side wall (6a) opposing an exterior cover (5) of the upperstructure (2) with a predetermined clearance (20) therebetween, and is made of synthetic resin and adapted to store hydraulic oil to be fed to hydraulic actuators. The hydraulic oil tank (6) has a gage (7) that enables a visual check on a level (8) of the hydraulic oil in the hydraulic oil tank (6) through a hole portion (5a) formed in the exterior cover (5). The gage (7) is installed in the side wall (6a) of the hydraulic oil tank (6), and has an internally-hollow protruding portion (7a) formed protruding in a direction toward the hole portion (5a) of the exterior cover (5) and a window portion (7b) comprised of a transparent member arranged at an end of the protruding portion (7a) and enabling the visual check on the level (8) of the hydraulic oil in the hydraulic oil tank (6).
