Abstract

A steering apparatus of the invention includes: a fixed bracket (3); an outer column (1); an arm portion (2); a column pipe (6); a steering shaft (A) including an upper shaft (8) rotatably attached to the column pipe (6) and a lower shaft (7) which is connected by an universal joint and in which a male shaft (71) and a female shaft (72) engage with each other so as to freely extend and contract; and a fastening tool (4). The arm portion (2) includes: bifurcated arm-shaped portions (21) that extend from a front side in the axial direction of the outer column (1) toward an outer side in the axial direction; a first linking portion (22) formed between the two arm-shaped portions (21) so as to protrude upward from upper edges of the arm-shaped portions (21); and a second linking portion (23) that protrudes downward from lower edges of the arm-shaped portions (21), and the second linking portion protrudes (23) from the arm-shaped portions (21) by a larger amount than the first linking portion (22).
