In a steering device, a restriction member urged by an urging member restricts rotation of an inner tube when the restriction member is at an inserted position at which the restriction member is inserted into a second opening of the inner tube through a first opening of an outer tube. When the inner tube moves to contract a steering column upon a secondary collision, a driving edge portion of the second opening drives the restriction member to a position at which the restriction member is retracted from the second opening against the urging member.
