Abstract

A utility vehicle includes an engine E provided for a body of the utility vehicle; an exhaust section 8 configured to discharge exhaust gas from the engine E; a belt-type continuously variable transmission device 31 configured to receive driving force from the engine E; an exhaust port 40 configured to discharge, from the belt-type continuously variable transmission device 31 , cooling air drawn into the belt-type continuously variable transmission device 31 to cool inside of the belt-type continuously variable transmission device 31 , the exhaust port 40 being on a first side of the exhaust section 8 ; and an air guide 41 disposed on a second side of the exhaust section 8 and configured to guide the cooling air from the exhaust port 40 to a cooling target.

Claims (38)

1 . A utility vehicle, comprising:

an engine provided for a body of the utility vehicle;

an exhaust section configured to discharge exhaust gas from the engine;

a belt-type continuously variable transmission device configured to receive driving force from the engine;

an exhaust port configured to discharge, from the belt-type continuously variable transmission device, cooling air drawn into the belt-type continuously variable transmission device to cool inside of the belt-type continuously variable transmission device,

wherein the exhaust port is on a first side of the exhaust section;

wherein an air guide is disposed on a second side of the exhaust section and configured to guide the cooling air from the exhaust port to a cooling target; and

wherein the air guide comprises a first guide plate and a second guide plate aligned in a front-back direction relative to the body.

2 . The utility vehicle according to claim 1 , further comprising:

a vertically swingable carrier box provided for the body,

wherein the exhaust port is below the carrier box,

wherein the first air guide plate is held by the body, and

wherein the second air guide plate is held by the carrier box.

3 . The utility vehicle according to claim 2 , wherein:

the second air guide plate is backward of the first air guide plate, and

the second air guide plate has a back portion in a form of an inclined portion inclined toward the exhaust port as the inclined portion extends backward relative to the body.

4 . The utility vehicle according to claim 2 , wherein:

the first air guide plate is in a form of a metal plate, and

the second air guide plate is made of a flexible material.

5 . The utility vehicle according to claim 1 , wherein:

the engine is provided with a water temperature sensor disposed on a side of the engine which side faces the exhaust section and configured to measure a temperature of cooling water for the engine, and

the cooling target is the water temperature sensor.

6 . The utility vehicle according to claim 1 , wherein:

the exhaust section is provided with an oxygen concentration sensor configured to measure a concentration of oxygen in the exhaust gas from the engine, and

the cooling target is the oxygen concentration sensor.

7 . A utility vehicle, comprising:

an engine provided for a body of the utility vehicle;

an exhaust section configured to discharge exhaust gas from the engine;

a belt-type continuously variable transmission device configured to receive driving force from the engine;

an exhaust port configured to discharge, from the belt-type continuously variable transmission device, cooling air drawn into the belt-type continuously variable transmission device to cool inside of the belt-type continuously variable transmission device,

wherein the exhaust port is on a first side of the exhaust section;

wherein an air guide is disposed on a second side of the exhaust section and configured to guide the cooling air from the exhaust port to a cooling target;

wherein the utility vehicle further comprises:

a vertically swingable carrier box provided for the body,

wherein the exhaust port is below the carrier box, and

wherein the air guide comprises:

a first air guide plate held by the body; and

a second air guide plate held by the carrier box.
