The engine cover has a side plate that has a rear edge with first and second rear edges. The second rear edge is a positioned above the first rear edge. The side plate has a first planar portion which includes the first rear edge and a second planar portion which includes the second rear edge. The side plate has a bent shape between the first and second planar portions. A ridgeline is disposed between the first and second planar portions and spans from the upper edge to the rear edge of the side plate. The side plate includes an attachment section which is attached to a vehicle body frame. The attachment section is positioned in the first planar portion adjacent to an intersection of the ridgeline and the rear edge of the side plate. ## Claims ### Claim 1 A bulldozer comprising: a vehicle body frame; a cab supported by the vehicle body frame; and an engine cover disposed in front of the cab, the engine cover including a side plate that has a rear edge, a first planar portion, a second planar portion and an attachment section, the first planar portion including a first rear edge of the side plate, the second planar portion including a second rear edge of the side plate, the second rear edge being positioned above the first rear edge, the side plate having a bent shape between the first planar portion and the second planar portion, a ridgeline being disposed between the first planar portion and the second planar portion and spanning from an upper edge of the side plate to the rear edge of the side plate, the attachment section being attached to the vehicle body frame, and the attachment section being positioned in the first planar portion adjacent to an intersection of the ridgeline and the rear edge of the side plate. ### Claim 2 (depends on 1) The bulldozer according to claim 1, wherein the side plate has an opening that communicates with an inner portion of the engine cover, and the attachment section is positioned behind the opening. ### Claim 3 (depends on 1) The bulldozer according to claim 1, wherein a center of gravity of the engine cover is positioned above the attachment section, and a distance between bottom edge of the side plate and the attachment section in a height direction of the bulldozer is equal to or more than a distance between the attachment section and the center of gravity of the engine cover in the height direction. ### Claim 4 (depends on 1) The bulldozer according to claim 1, wherein the vehicle body frame has a frame body supporting the cab and a frame side attachment section to which the attachment section is attached, and the frame side attachment section protrudes upward from the frame body. ### Claim 5 (depends on 1) The bulldozer according to claim 1, wherein the attachment section is positioned at the same height as the intersection of the ridgeline and the rear edge of the side plate. ### Claim 6 (depends on 1) The bulldozer according to claim 1, wherein the upper surface of the engine cover is inclined downward with a forward inclination. ### Claim 7 (depends on 1) The bulldozer according to claim 1, wherein the rear edge of the side plate has a convex shape protruding to the rear at the intersection of the first rear edge and the second rear edge. ### Claim 8 (depends on 2) The bulldozer according to claim 2, wherein the upper surface of the engine cover is inclined downward with a forward inclination. ### Claim 9 (depends on 3) The bulldozer according to claim 3, wherein the upper surface of the engine cover is inclined downward with a forward inclination. ### Claim 10 (depends on 4) The bulldozer according to claim 4, wherein the upper surface of the engine cover is inclined downward with a forward inclination. ### Claim 11 (depends on 5) The bulldozer according to claim 5, wherein the upper surface of the engine cover is inclined downward with a forward inclination.
