Document Type and Number:
Japanese Patent JP6922716
Kind Code:
B2
Abstract:
Provided is a steering system in which a cylindrical portion of a cover member is less likely to buckle when the cover member is attached to an input shaft even if the length of the cylindrical portion of the cover member to be attached to the input shaft is increased. A steering system (1) includes a pinion shaft (22) that meshes with a rack shaft (4), an input shaft (21) configured to rotate in response to a steering operation, a torsion bar (23) that couples the input shaft (21) and the pinion shaft (22) together, a fixing pin (24) that fixes the torsion bar (23) to the input shaft (21), a housing (6) having a first housing portion (61) that houses a part of the input shaft (21), and a cover member (7) having a cylindrical portion (71) externally fitted to the input shaft (21) protruding from the first housing portion (61), and a disc portion (72) that covers an end face (612a) of the first housing portion (61). A through hole (21a) where the fixing pin (24) is inserted is formed in the input shaft (21). On the cylindrical portion (71) of the cover member (7), a plurality of annular lips (711-715) are provided, except for a portion (71c) that faces each of openings (21b) of the through hole (21a), on one side and the other side in an axial direction with respect to the portion (71c).
