Abstract: Providing a vehicle torque limiter device enabling acquisition of a hysteresis torque with a simple structure. Since a friction force F1 generated on friction surfaces between a pressure plate 80 and a first friction material 88 is smaller than a friction force F2 generated on friction surfaces between a lining plate 76 and the first friction material 88, when a torque T is input to a damper device 38, a slip first occurs between the pressure plate 80 and the first friction material 88, and the lining plate 76 and the first friction material 88 integrally rotate. In this case, a hysteresis torque T1 is generated based on the friction force between the pressure plate 80 and the first friction material 80. Since a torque limiter mechanism 68 also acts as a hysteresis mechanism in this way, the torque limiter mechanism 68 is realized that can generate the hysteresis torque with a simple structure.
