Patent ID: 8070334

Claim:
A work machine comprising: an operator's cab; an engine hood disposed in front of the operator's cab; an exhaust pipe projecting upwards from the engine hood; a first headlight and a second headlight spaced apart in a lateral direction of the work machine at a front part of the operator's cab to illuminate a front side of the work machine, the first and second headlights being disposed so that optical axes of the first and second headlights mutually intersect at a position directly above the engine hood on a longitudinal center axis of the engine hood and the position laterally away from the exhaust pipe when viewed in a top plan view; a third headlight disposed between the first headlight and the second headlight in the lateral direction to illuminate the front side of the work machine; and a coupling member mounted to the operator's cab to fix the first, second and third headlights to the operator's cab, the exhaust pipe and the first headlight being aligned along a vertical plane parallel to the longitudinal center axis of the engine hood when the work machine is placed on a level surface, the third headlight being arranged with respect to the first and second headlights so that an acute angle formed between a horizontal plane and an optical axis of the third headlight is smaller than acute angles formed between the horizontal plane and the optical axes of the first headlight and the second headlight when the work machine is placed on the level surface, the coupling member including a first surface supporting the first headlight, a second surface supporting the second headlight, and a third surface supporting the third headlight, a difference between an inclination angle of the first surface with respect to the horizontal plane and an inclination angle of the third surface with respect to the horizontal plane being substantially equal to a difference between the acute angle formed between the optical axis of the first headlight and the horizontal plane and the acute angle formed between the optical axis of the third headlight and the horizontal plane, and a difference between an inclination angle of the second surface with respect to the horizontal plane and the inclination angle of the third surface with respect to the horizontal plane being equal to a difference between the acute angle formed between the optical axis of the second headlight and the horizontal plane and the acute angle formed between the optical axis of the third headlight and the horizontal plane.
