<p>A shock absorbing steering device (1) for vehicle includes an intermediate shaft (5) that couples a steering shaft (3) and a steering gear (11). The intermediate shaft (5) includes a hollow accordion portion (40) allowed to undergo plastic deformation. The accordion portion (40) has plural pairs of crest portions (41, 41A, or 41B) and trough portions (42) disposed alternately in an axial direction (S1). At least in a part of the accordion portion (40) in the axial direction (S1), a height (D1 and D2) from bottoms (44) of the trough portions (42) to apexes (43) of the crest portions (41, 41A, or 41B) is set relatively high in one of first and second parts (45 and 46) of the accordion portion (40) opposing in a radial direction (R) and relatively low in the other one of the first and second parts (45 and 46).
