1. A steering device comprising:
a pipe into which a steering shaft is inserted to be rotatable around an axis along a front-rear direction;
a housing supported by a vehicle body and configured to support the pipe to be movable in the front-rear direction;
a telescopic mechanism configured to move the pipe with respect to the housing in the front-rear direction; and
a load absorbing mechanism configured to connect the pipe and the telescopic mechanism to each other,
wherein the telescopic mechanism includes
an actuator coupled to the housing, and
a feed mechanism having an engaging portion coupled to the actuator and an engaged portion coupled to the load absorbing mechanism and engaged with the engaging portion in the front-rear direction and configured to transmit a driving force of the actuator to the pipe via the engaging portion and the engaged portion, and
the load absorbing mechanism includes
an extending portion provided in any one member of the pipe and the feed mechanism and extending in the front-rear direction,
a sliding portion provided on a first side in a left-right direction with respect to the extending portion in the other member of the pipe and the feed mechanism, and configured to plastically deform the extending portion by moving relative to the one member while sliding on a side surface of the extending portion which faces the first side in the left-right direction, when a load acting on the pipe is a predetermined value or greater, and
a restriction portion provided on a second side in the left-right direction with respect to the extending portion in the other member and configured to be movable in concert with the sliding portion, when the load acting on the pipe is the predetermined value or greater, and to restrict movement or deformation of the extending portion to the second side in the left-right direction.
