PROBLEM TO BE SOLVED: To provide a mono-link type axle box supporting device capable of reducing a lateral pressure in a high speed railway vehicle such as the Shinkansen. SOLUTION: In the axle box supporting device 11 of the truck for the high speed railway vehicle, a shaft spring 14 is arranged between an upper surface of the axle box 2 and an end part of a side beam 1, and the side beam 1 and an inner side surface of the axle box 2 are joined by one link 12 in which rubber members, for example, rubber bushings 13a, 13b are interposed at both ends. The link 12 is mounted while being offset by any one of (1) 3 to 10% of link length L in a vehicle vertical direction, (2) 5 to 20% of link length L in a vehicle width direction, and (3) 3 to 10% of link length in the vehicle vertical direction and 5 to 20% of link length L in the vehicle width direction.
