PROBLEM TO BE SOLVED: To provide an improved desirable axle spring gear, by changing a spring constant by a horizontal-directional angle by an inexpensive and rational means, without causing a large increase in a mold cost and an increase in manufacturing manhours, nor causing no increase at all. SOLUTION: This axle spring gear is interposed with an elastic part 3 layered alternately with intermediate hard cylinders 9, 10 and elastic layers 11-13 along radially inward and outward directions, while being concentric or substantially concentric to an axis P, between a main shaft 1 and an outer cylinder 2 having the axis P same or substantially same thereto each other, and the axle spring gear is equipped with an elastic regulating mechanism 4 engaged loosely with an outer cylinder side member 14 fixation-supported to the outer cylinder 2 and the main shaft 1, via an elastic material D, while having an engaging axis X along the axis P.
