PROBLEM TO BE SOLVED: To reduce the size, weight and cost of a life guard device for eliminating obstacles on railroad tracks. SOLUTION: The life guard device 30 includes, from the front side in the running direction, a life guard member 31 and a connecting mechanism 40. The connecting mechanism 40 includes a distribution member 33 and two connecting parts composed of support members 47, energy absorbing members 35 and rods 37, respectively and disposed in parallel with each other. The life guard member 31 is disposed along the width direction of the vehicle body and turnably connected via first pins 32. The center portion in the width direction of the life guard member 31 is connected via a pin 34 to the distribution member 33, and the energy absorbing members 35 for absorbing impact load are arranged via the support members 47. The energy absorbing members 35 are connected via rods 37 and second pins 38 to the lower surface 3b of an underframe. If obstacles collide with any position in the width direction of the life guard member 31, regardless of the collided position, the impact load is transmitted uniformly via the distribution member 33 to the energy absorbing members 35, 35.
