An obstacle detector of a construction vehicle includes a brake mechanism which includes: a first hydraulic closed circuit including a pump for rolling, which is equipped with a swash plate, and a motor for rolling, which is connected with the pump for rolling; a second hydraulic closed circuit including a first hydraulic passage communicating with one side of the pump for rolling and a second hydraulic passage communicating with another side of the pump for rolling, to actuate the swash plate; and a neutral valve provided in the second closed circuit. When an emergency brake is activated, at least one of a compressive returning force to compress a low-pressure side of the tilted swash plate for returning the swash plate to a neutral position and a decompressive returning force to decompress a high-pressure side of the swash plate for returning the swash plate to the neutral position is generated.
