To prevent derailment of a high-speed vehicle on a curved railway track of a railway track and derailment due to an earthquake.Escape prevention device main bodies (8) are each installed on left and right sides of a lower part of a bogie main body (5) of a vehicle, and in wide grooves (9) provided in the main bodies (8), escape preventing thick plates (10) are housed so as to be vertically slidable. When the vehicle runs on a railway track curved to the right, a centrifugal force causes a left flange part (7) to ride on a left rail (1), the left escape prevention device main body (8) moves obliquely upward toward the rail (1), a front surface (11) of the escape preventing thick plate (10) collides with a side surface (3) of a rail head (2), an L-shaped hook part (13) of the escape preventing thick plate (10) collides with a lower surface of an eave (4) of the rail head (2), and the escape prevention device main body (8) further floats, thereby cutting a positioning pin (14) between the escape prevention device main body (8) and the escape preventing thick plate (10). The escape prevention device main body (8) is guided by the escape preventing thick plate (10), sprung up almost vertically by 10 cm or more, and then, dropped, and the wheel (6) is returned onto the rail (1), and the derailment is prevented.
