Abstract: A rear portion is arranged in the rear of a front portion, and has a width smaller than a width of the front portion in a plan view. A wall portion extends from the rear portion outward in a width direction toward the front portion and includes two walls opposed to each other in a fore/aft direction with a gap lying therebetween, in a plan view. Electric components are arranged in the gap and project into an indoor space of a cab from the gap through a through hole formed in the front wall. In a plan view, a foremost portion of the electric components is located in the rear of a foremost normal located foremost among normals to a line connecting a front end and a rear end of a doorway, which intersect with the front wall.
