Embodiment Construction

[0057] Figure 1 ~ Figure 4 This is an example of the embodiment of the present invention. The steering device of this example is installed to adjust the steering wheel 1 according to the driver's physique and driving posture (refer to Image 6 A tilting mechanism in the vertical position of ), the steering device includes a steering column 6a, a steering spindle 5a, a support bracket 15a, a displacement bracket 14a, a cam device 27a, a pair of tilting long holes 18a, and a pair of through holes 19a.

[0058] The steering column 6a consists of a tilting shaft 13 (refer to Image 6 ) The tilting shaft 13 is supported so as to be capable of swinging displacement, and the tip portion of the tilting shaft 13 is fixed to the vehicle body 12 in a state arranged in the width direction. The steering spindle 5a is rotatably supported on the inner side of the steering column 6a, and the steering wheel 1 is fixed to the rear end of the steering spindle 5a.

[0059] The support bracket 15a is f...

Abstract

The present invention realizes a configuration capable of easily judging whether or not the combination of the driving side cam and the driven side cam is appropriate. Driven side grooves (47) are formed at two positions on the outer peripheral surface of the driven side cam (30a) which are radially opposite sides, and are recessed radially inward in the entire axial direction. In the outer peripheral surface of the driving side cam (29a), the portion in which the phase in the circumferential direction coincides with the driven side groove (47) in the locked state is formed in a state of being recessed radially inward in the entire axial direction. The first driving side groove (45), in the unlocked state, the portion in which the phase in the circumferential direction coincides with the driven side groove (47) is formed in a state of being recessed radially inward in the entire axial direction Second drive groove (46).

Description

Technical field [0001] The present invention relates to a cam device, which is, for example, incorporated and used in a position adjustment device of a steering wheel, and the position adjustment device of the steering wheel is used to make the height position of the steering wheel adjustable. Background technique [0002] Image 6 Represents a conventionally known steering device for automobiles. The steering wheel 1 is supported and fixed to the rear end of a steering spindle 5, and the steering spindle 5 is rotatably supported by the steering column 6 in a state where a cylindrical steering column 6 is inserted in the axial direction. The front end of the steering main shaft 5 is connected to the rear end of the intermediate main shaft 8 via a universal joint 7, and the front end of the intermediate main shaft 8 is connected to the input shaft 3 via another universal joint 9. If the driver operates the steering wheel 1, the rotation of the steering wheel 1 is transmitted to th...
