1. A steering device comprising:
a tube in which a steering shaft is attached so as to be rotatable about an axis of the steering shaft;
a housing that holds the tube movably in an axial direction along an axis of the steering shaft;
a moving member;
a drive device that is attached to the housing and moves the moving member in the axial direction;
a first fixing member that is provided on one first member that is either one of the tube and the moving member, and fixes the tube and the moving member to each other; and
a restriction portion that is provided on a second member that is either another one of the tube and the moving member, is separated from the first fixing member in the axial direction, and restricts the tube and the moving member relatively rotating about a rotational center axis intersecting an axis of the steering shaft,
wherein
when predetermined load acts on the tube in a direction in which the first member is relatively moved in a first direction included in the axial direction with respect to the second member, one of either the first member or the second member plastically deforms a deformation portion provided on another of either the first member or the second member, along with movement of the first member with respect to the second member, wherein
the first fixing member passes through a first hole provided in the first member, and a first notch provided in the second member and opened in the first direction, and fixes the tube and the moving member to each other,
the restriction portion passes through a second notch provided in the first member and opened in a second direction opposite to the first direction, and restricts the tube and the moving member from relatively rotating about the rotational center axis, and
when the predetermined load acts on the tube in a direction in which the first member is relatively moved in the first direction with respect to the second member, the first fixing member is released from the first notch in the first direction, and the restriction portion is released from the second notch in the second direction.
