するロツク機構。 In a telescopic steering device having an outer telescopic tube and an inner top shaft that are connected to each other so as to be slidable relative to each other in the axial direction, the top shaft has upper and lower ends closed on the outer circumferential surface of the top shaft, and a shaft that extends deeply toward the bottom of the shaft. An inclined keyway is provided in the axial direction of the shaft, a locking key movable in the longitudinal direction of the groove and having a protrusion on the outer surface is housed in the keyway, and the locking key is sunk into the keyway at the lower end of the keyway, The locking mechanism is characterized in that, at the upper end of the keyway, the projection is set to a size that allows it to protrude from the keyway and bite into the inner circumferential surface of the telescopic tube.
