In a steering system including a lock mechanism, at a time of locking, a first cam (21) that is rotated together with a lock shaft (19) generates a pressing force for pushing up an inner tube (12) in an upward tilt direction. A second cam (22) that is rotated together with the lock shaft (19) presses an abutting portion (27) of an urging member (25) in a downward tilt direction. The abutting portion (27) of the urging member (25) applies a pressing reaction force in the upward tilt direction, to the second cam (22). The pressing reaction force serves as a force for pushing up the first cam (21) in the upward tilt direction, through the second cam (22) and the lock shaft (19). |
