It is configured to be.
[17] However, in the conventional device capable of adjusting the inclination angle, the gear formed on the shoe coupled to the tilt housing has an interval of 4 degrees, and the gear spacing of the shoe coupled to the tilt housing is rigid when finely formed. Since the deflection may occur due to the lack of the engaging pieces 21 assembled in the support housing, there is a disadvantage in that the gear formed on the shoe is more minutely formed.
[18] When the inclination angle of the steering column is not finely adjusted, there is a problem that the steering wheel may not be positioned at the angle desired by the driver.
[19] The present invention is to overcome the above-mentioned conventional problems,
[20] One object of the present invention is to mount a lever having a locking shaft connected by a lever mounting frame to a support housing on which the lower shaft is mounted, and to form a gear that meshes with the gear of the shoe in the support housing to pull the lever to tilt the upper shaft to be mounted. It is to provide a steering column inclination adjusting device to be able to move the position of the shoe mounted on the housing to finely adjust the inclination in accordance with the angle of the axis and the direction of the shaft to which the steering wheel is mounted.

[30] The tilt housing 110 has a cylindrical shape and has a protrusion protruding to one side at a central portion thereof, and an insertion hole 112 is formed at the protrusion to which the shoe 130 described later in the lateral direction is coupled. In addition, a coupling hole 111 is formed at a lower portion of the tilt housing 110 so that the support housing 120 and the lever mounting frame 141 described below in the lateral direction may be coupled through the coupling pin 113. .
[31] In addition, the support housing 120 is a rectangular cylinder having an upper surface and a lower surface opened, and coupling holes 121 corresponding to the coupling holes 111 formed in the tilt housing 110 are formed at both upper sides thereof. Gears 122 corresponding to the gears 131 formed on the shoe 130 described below are formed at both front edges. In addition, a spring (not shown) is mounted between the front part of which the gear 122 is formed and the protrusion part of which the insertion hole 112 of the tilt housing 110 is formed to connect the tilt housing 110 and the support housing 120.
