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.

摘要： A steering column device includes an inner tube (120), a housing (130), and a lock mechanism (150) configured. The lock mechanism (150) includes a first engagement member (151), a second engagement member (152), a first urging member (153), a second urging member (154), a cam member (155) configured to rotate about a rotation axis extending in a direction in which the first urging member (153) and the second urging member (154) are arranged such that the second urging member (154) serving as a follower is moved in the direction in which the first urging member (153) and the second urging member (154) are arranged to change a magnitude relationship between an urging force of the first urging member (153) and an urging force of the second urging member (154), and an operation lever (156) configured to operate the cam member (155).
