<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) and trough portions (42, 42A, 42B, or 42C) disposed alternately in an axial direction (S1). At least in a part of the accordion portion (40) in the axial direction (S1), a depth (D1 and D2) from apexes (43) of the crest portions (41) to bottoms (44) of the trough portions (42, 42A, 42B, or 42C) includes a first depth (D1) corresponding to a part (45) of the accordion portion (40) in a circumferential direction (T) and a second depth (D2) corresponding to a rest part (46) of the accordion portion (40) in the circumferential direction (T). The first depth (D1) and the second depth (D2) are different from each other.</p> |
