Abstract:
A wheel loader, which is a construction machine, includes: a rear vehicle body and a front frame; an operating device provided at the front frame; and a working lamp unit attached to a sidewall of the rear vehicle body. The working lamp unit has a light source and a bracket including a downward illuminating portion that covers at least an upper part of the light source and that protrudes more in the light illumination direction than a lens surface of the light source and that is inclined downward with respect to a horizontal direction. Thus, there is obtained a construction machine including a working lamp, in which visibility can be ensured both in a distant area and in an area near the construction machine.
