A steering column device includes a cylindrical inner jacket; a cylindrical outer jacket in which the inner jacket is slidably inserted; and a steering shaft rotatably supported in the inner jacket and the outer jacket. The outer jacket is divided into a molded first half member and a molded second half member at a plane including an axis of the outer jacket. According to this steering column device, in molding the outer jacket, it is not necessary to set a draft for a core along the axial direction on the inner circumferential surface of the outer jacket.
