摘要：PROBLEM TO BE SOLVED: To reduce weight and cost by using a single axle bogie without impairing riding comfortableness. SOLUTION: A wheel shaft 16 having wheels 15 in both ends thereof is supported by a bogie frame 14 through a shaft spring 17. A vehicle body 11 is supported on the bogie frame 14 through a main bolster spring 12 and an auxiliary bolster spring 13. Connection points 12a and 13a of the main bolster spring 12 and the auxiliary bolster spring 13 to the bogie frame 14 are displaced from the connection point 17a of the shaft spring 17 to the bogie frame 14. The connection point 13a of the auxiliary bolster spring 13 to the bogie frame 14 is displaced from the connection point 12a of the main bolster spring 12 to the bogie frame 14. Moment in the bogie frame 14 at each connection point 17a, 12a and 13a of shaft spring 17, the main bolster spring 12 and the auxiliary bolster spring 13 are balanced.
