摘要

A steering device includes: a steering shaft and a column jacket that are telescopically adjustable in an axial direction; a lock member that advances to an advance position at which the lock member is engaged with one of holes of a lock plate and that retreats to a retreat position at which the lock member is disengaged from the hole of the lock plate; an operation member that is mechanically separated from the lock member; a biasing member that constantly biases the lock member toward the advance position; and a transmission member that moves the lock member to the retreat position against a biasing force of the biasing member in accordance with operation of the operation member.
