摘要： A steering device includes a cylindrical support tube (17) that rotatably supports a steering shaft (2), a speed reducer (20) configured to apply a torque to the steering shaft (2), and a housing (18) that includes a cylindrical portion (41) housing the speed reducer (20). A flange (31) of the support tube (17) and the cylindrical portion (41) are disposed coaxially and coupled to each other with a bolt (30). A bearing support member (50) is fitted to an inner peripheral surface of the cylindrical portion (41). The steering shaft (2) extends through the bearing support member (50). A bearing (71) is disposed between an outer peripheral surface of the steering shaft (2) and an inner peripheral surface of the bearing support member (50). The bearing support member (50) includes a deformation allowing portion (55, 56, 59) configured to allow elastic deformation of the bearing support member (50) in a radial direction.
