Abstract

A steering system (1) is configured to prevent twisting between a bracket (5) and a capsule (8) when the bracket (5) is detached from the capsule (8) at the time of a secondary collision. The steering system (1) includes a plate member (14) provided in the upper bracket (5) and the capsule (8). The plate member (14) has a cutout groove (23) that is a recess opened toward the upstream side in a moving direction (A). The capsule (8) has a first end portion (27), a second end portion (28), and a side end portion (29) located between the first end portion (27) and the second end portion (28). The capsule (8) is fitted in the cutout groove (23) to position the upper bracket (5) with respect to a vehicle body. The first end portion (27) and the second end portion (28) retain a peripheral edge portion (14E) of the plate member (24), which defines the cutout groove (23), in an up-down direction (Z). The lateral end portion (29) does not retain the peripheral edge portion (14E). At the time of a secondary collision, the capsule (8) is removed from the cutout groove (23) toward the upstream side to allow the upper bracket (5) to move toward the downstream side.

Description

technical field [0001] The present invention relates to steering devices. Background technique [0002] As shown in Japanese Unexamined Patent Application Publication No. 2012-171585 described below, in a conventional vehicle steering device, the vehicle rear side of a steering column is fixed to a vehicle-side mounting and holding portion via a pair of fixing plate portions of a fixing bracket. In each fixing plate portion, the notch groove is formed so as to open on the vehicle rear side in the fixing plate portion. A pod member is coupled to each of the fixing plate portions, and the pod member sandwiches a portion sandwiching the notch groove (peripheral portion of the notch groove in the fixing plate portion) up and down in the vehicle width direction. In the case of a secondary collision, with the pod member left in the attachment holding portion, the fixing bracket is detached from the attachment holding portion toward the vehicle front side. Thereby, it is possible...
