Problems solved by technology

[0006] However, for example, when the operating lever is rotated by the driver's operation, if the end of the tension coil spring moves in the locking hole while contacting the inner peripheral surface of the locking hole, a creeping phenomenon may occur.
As a result, for example, rattling noises may occur and an uncomfortable feeling may be experienced by the driver
In addition, such a problem may similarly occur in a steering column device configured to be able to adjust only either one of the tilt position and the telescopic position.

Embodiment Construction

[0029] Hereinafter, one embodiment of the steering column device will be described with reference to the drawings. The steering column device 1 of the present embodiment constitutes a part of an electric power steering device. The steering column device 1 is mounted on the vehicle such that its axial direction is along the front-rear direction of the vehicle. Therefore, in the following description, the figure 1 The left inner side in is set as the front side of the vehicle, and the figure 1 The right near front side in is set as the vehicle rear side.

[0030] Such as figure 1 and figure 2 As shown, the steering column device 1 includes: a column shaft 3 constituting a part of the steering shaft 2; and a steering column 4 that accommodates the column shaft 3 so as to be rotatable. A steering wheel 5 is coupled to an end portion of the column shaft 3 on the rear side of the vehicle. On the other hand, an intermediate shaft constituting a part of the steering shaft 2 is ...

Abstract

A steering column device (1) is provided by the invention and includes a locking mechanism (91). The lock mechanism (91) is provided with: an operation lever (92) that rotates integrally with the fulcrum shaft (53) around the fulcrum shaft (53); and a wire spring (131) provided between a vehicle body-side bracket (51) and the operation lever (92). The operation lever (92) has a lever-side locking hole (106) into which a first end portion (133) of the wire spring (131) is inserted. The lever-side locking hole includes: a first hole (141) having an inner diameter larger than a wire diameter of the first end portion (133); and a second hole (142) which has a larger inner diameter than the first hole and is continuous with the first hole. The first hole is provided closer to the vehicle body-side locking hole (69) than the second hole. The width of an opening in a connection portion between the first hole and the second hole is larger than the wire diameter of the first end portion.

Description

technical field [0001] The present invention relates to steering column devices. Background technique [0002] For example, as described in JP 2014-83906, there is known a steering column device configured to be able to adjust the height position (hereinafter referred to as tilt position) of the steering wheel and the front-rear position (hereinafter referred to as telescoping position) of the steering wheel. Such a steering column device is supported by the vehicle body via a support mechanism. [0003] The support mechanism includes: a bracket on the column side fixed to the steering column; a bracket on the vehicle body side fixed to the vehicle body; and a support shaft connecting the bracket on the vehicle body side and the bracket on the column side. For example, the bracket on the vehicle body side has an elongated insertion hole elongated in the vehicle up-down direction, and the bracket on the column side has an elongated insertion hole elongated in the vehicle fro...
