1. An industrial vehicle comprising:
a counterweight located at a rear portion of a vehicle body;
a radiator disposed in front of the counterweight;
a radiator fan configured to generate cooling air flowing behind the vehicle body; and
an exhaust pipe disposed inside the counterweight to release exhaust gas from an engine into the atmosphere,
wherein the exhaust pipe has a tail pipe extending in a vehicle width direction of the vehicle body,
wherein a closure part configured to close an opening of the tail pipe is provided at a tip end portion of the tail pipe,
wherein a first exhaust port configured to discharge the exhaust gas rearward from the vehicle body and a second exhaust port configured to discharge the exhaust gas rearward from the vehicle body at a tip end side of the tail pipe with respect to the first exhaust port are provided in a circumferential surface portion of the tail pipe,
wherein the first exhaust port and the second exhaust port are disposed in a region where the cooling air flows, and
wherein a throttling part configured to change a flow path area for the exhaust gas is disposed between the first exhaust port and the second exhaust port in the tail pipe,
wherein the throttling part is formed of a plate-shaped member having substantially a U shape which is fixed to the tail pipe, and
wherein the plate-shaped member of the throttling part has an inclination part inclined with respect to a front-rear direction and a vehicle width direction of the vehicle body on a side of the second exhaust port, and
wherein the closure part has an inclination portion inclined with respect to the front-rear direction and the vehicle width direction of the vehicle body so as to taper from a side opposite to the first exhaust port and the second exhaust port toward a side of the first exhaust port and the second exhaust port.
