Claim:
1. A work vehicle, comprising: a condenser for cooling a cooling medium used in an air conditioner; a compressor for compressing said cooling medium for said air conditioner; a fan for cooling said condenser; a variable mechanism capable of changing a number of rotations of said fan; a fan control unit for controlling said variable mechanism; an outside air temperature sensor for detecting an outside air temperature; and a storage unit for storing a plurality of control maps for setting the number of rotations of the fan to respective different numbers of rotations of the fan in accordance with the outside air temperature detected by said outside air temperature sensor, wherein said fan control unit controls said variable mechanism in accordance with one control map selected from said plurality of control maps stored in said storage unit based on an operating state of said air conditioner, to control the number of rotations of said fan, wherein said fan control unit determines the operating state of said air conditioner by detecting a state of an ON/OFF drive signal which controls an ON/OFF operation of said compressor, and said fan control unit controls said variable mechanism in accordance with said ON/OFF drive signal.
