Abstract

PURPOSE: To easily assemble a turning lever to a lever holder with a simple structure, and improve workability and economy by eliminating a pulling out preventing member such as a fixing nut, a split pin. CONSTITUTION: A large diametral pivot hole 11 is opened to an upper lever holder 4b. A small pivot hole 12 is coaxially opened to a lower holder 4c with the large diametral pivot hole 11, and insertion recessed parts 13, 13a oppositely arranged along the small diametral pivot hole 12. Fitting recessed parts 14, 14 are formed outside the small diametral pivot hole 12 on the lower surface of the lower lever holder 4c. A large diametral shaft part 8a extendedly interpolated between the large diametral pivpot hole 11 and a rotary hole 10 and a small diametral shaft part 8b extendedly interpolated between the rotary hole 10 and the small diametral pivot hole 12, are arranged to a pivot 8. Fitting projecting parts 8c, 8c fitted in the fitting recessed parts 14, 14 through the insert recessed part 13, are arrangted at the end side part of the small diametral shaft part 8b. A helical spring 15 is compressively arranged between the end surface of the large diametral shaft part 8a and the upper surface of the lower lever holder 4c.

2. Description of the Related Art As a general support structure of an operating lever for activating a brake or a clutch of a motorcycle or the like, there is, for example, the one disclosed in Japanese Utility Model Publication 3-57591. With this support structure, the mounting base of the operating lever is inserted between two parallel lever holders that project substantially horizontally from the cylinder body of the hydraulic master cylinder, and the pivot is inserted through the mounting base and the upper lever holder. Then, a male screw at the tip of the pivot is screwed to the lower lever holder and the fixing nut to pivotally support the operation lever.

Further, in Japanese Utility Model Laid-Open No. 56-72918, a mounting base of a rotating lever is inserted between two parallel lever holders, and a spiral spring is externally attached to the pivot, and the spiral spring is pivoted. While compressing between the head flange and the one lever holder, insert the pivots into both lever holders and the mounting base of the rotating lever, and prevent the tip of the pivots from slipping off with the cotter pin. A structure is shown in which a rotating lever is pivotally supported while being elastically urged toward the insertion side by a spiral spring.

However, in the former support structure, the male screw of the pivot tip is once screwed into the lower lever holder, and then the pivot of the pivot is further projected to the lower surface of the lower lever holder. This requires a double screwing operation of screwing a fixing nut to the screw, and the assembling work is complicated and troublesome. Also,
The lower lever holder must be formed with a highly accurate reaming process or tapping to form a female screw hole, which is disadvantageous in terms of workability and cost.

On the other hand, in the latter support structure, the head flange of the pivot and the spiral spring are projected to the outside of the lever holder, and further, the elastic force of the spiral spring causes the split pin at the tip to move. Since it is pushed back to the insertion side to the position where it abuts the outer surface of the lever holder, the amount of overhang becomes even larger and it is difficult to apply if there is not enough mounting space.

As described above, according to the constitution of the present invention,
The rotation lever can be attached just by inserting the pivot and rotating, so compared to the conventional one in which the male screw of the pivot is double screwed to the lever holder and the fixing nut,
The installation work can be simplified and the installation time can be shortened. In addition, it is economical because it does not require reamer processing that requires high processing accuracy, processing such as tapping, and retaining members such as fixing nuts and split pins, and it is economical because the retaining member is omitted. Since it can be done with one hand, it is excellent in installation workability in places where it is difficult to see visually.

Further, since the turning lever can be easily removed with one touch as in the case of mounting, it is particularly suitable for the replacement of the lever in a motorcycle race, which requires the reduction of the pit-in time, and for the replacement of the lever of a commercially available car. Even if there is, the work time can be shortened and the labor cost can be reduced.

Further, the elastic material is a spiral spring, one end of the spiral spring is locked to the pivot, and the other end is locked to the second lever holder, so that the torsion force of the spiral spring is When the pivot is rotated in the pull-out direction by imparting to the pivot so that the fitting protrusion of the pivot matches the fitting recess of the second lever holder,
Since the torsion force of the spiral spring acts as a drag force, it becomes possible to more reliably prevent the pivot from coming off.

Further, by locating the base end surface of the large-diameter shaft portion of the pivot in the large-diameter pivot hole of the first lever holder, there is no extra projecting portion outside the lever holder, and there is no room for mounting space. It is also applicable in cases. Further, when the protective cap is attached to the opening of the large-diameter pivot hole, the protective cap protects the pivot and effectively prevents the pivot from coming off even if an external force acts on the outer surface of the first lever holder. In addition, it is possible to prevent dust and rainwater from entering around the pivot axis.
