To solve a problem wherein a wrecking arm mounting device cannot be also arranged on a front side since a rear wheel and a jack device interfere with each other at storage of an outrigger when an attempt is made to position an outrigger device on a front side relative to a vehicle advancement direction in a conventional wrecker truck.

In the wrecker truck having the outrigger device 11 ground-contacted with a rear end part of the vehicle while projected to left/right sides of the vehicle and the wrecking arm mounting device 2 on the rear end part of the vehicle, the outrigger device 11 is provided with a turning arm 13 turned in a horizontal direction making a rotation shaft 15 as a center; and the jack device 14 at a distal end of the turning arm. The turning arm 13 is turned/stored to a vehicle side in the traveling state of the wrecker truck, and positions of both ends of the turning arm 13 in the traveling state are arranged at sides of the wrecking arm mounting device 2 or at front sides than the side relative to the vehicle advancement direction.
