Abstract

PURPOSE:To lock a steering wheel central part with a simple mechanism, by installing a fixed cylindrical member on an outer circumferential part concentrically with a steering shaft, while installing a rotary member in a steering wheel part free of rotation around the cylindrical member, and winding a belt round between both members. CONSTITUTION:A steering shaft 4 is rotatably supported on a steering column 2 in a column cover 1 via a bearing 3, and rotation of a steering wheel 5 is transmitted to the shaft 4 by a boss 5a of the steering wheel. A fixed cylindrical member 7 is installed on an outer circumferential part concentrically with the steering shaft 4, and a belt 10 is wound round between the shaft 4 and the rotary member 12 installed in the steering wheel boss 5a. A fixed pad 13 is supported on a steering wheel central part via a ring member 9 of the same form with the fixed cylindrical member, and a part of the belt 10 is wound round. According to this method, the central part is clamped by a simple mechanism without using a planetary gear mechanism or the like.

良等を招く欠点をもっている。BACKGROUND ART In recent years, electronic control of control devices for automobiles and the like has progressed, and the operation units for these devices have been placed near the steering wheel so that they can be easily operated by the driver. The steering pad, which is the center of the steering wheel, is mentioned as one of the operating parts, but since the steering pad generally rotates together with the steering wheel, in order to install the operating part here, the steering pad must be attached to the steering wheel. Regardless of rotation, the steering pad must be kept stationary by some means. Therefore, various methods have been considered as means for fixing the steering pad, but all of the existing methods have drawbacks such as complicated structures, time-consuming assembly operations, increased costs, and malfunctions.

A vibrator 2 is disposed inside the vibrator 2. A steering shaft 4 rotatably passes through the vibrator 2 via a bearing 3, and a boss portion 5a of a steering wheel 5 is fixed to the steering shaft 4 with a nut 6. ing. A ring-shaped fixing member 7 is fixed to the end of the vibrator 2, and a ring-shaped fixed member 9 having the same diameter as the fixing member 7 is attached to the tip of the steering shaft 4 via a bearing 8. It is rotatably attached so as to face the fixed member 7. Engaging portions 7a and 9a, such as narrow grooves, are formed on the outer peripheral surfaces of the fixing member 7 and the fixed member 9, respectively.

A rotating member 12 is attached to this support shaft 11, and a support shaft such as a narrow groove formed on the outer peripheral surface of the rotating member 12 is provided. The inner circumferential surface 10a of the timing belt 10 is engaged with the joint portion 12H.

れ回転しない。Figure 2 shows the fixing member 7 and the fixed member 9 in Figure 1 above.
, is a diagram showing the principle of interlocking of the timing belt 10 and the rotating member 12. When the steering wheel 5 rotates together around the steering shaft 4, the rotating member 12 attached to the support shaft 11 also rotates around the steering shaft 4, for example. Move in the direction of arrow A. At this time, since the fixed member 7 is fixed to the car body by the vibrator 2, the rotating member 1
2 will be transferred on the timing belt 10 in the direction of arrow B. On the other hand, since the fixed member 9 is connected to the steering shaft 4 via the bearing 8, it is free from rotation of the steering shaft 4, but since it is engaged with the timing belt 10, it is integral with the fixed member 7. is rotated and does not rotate.
