  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. 1 is a cross-sectional view taken along the line II of FIG. 2, FIG. 2 is a side view of the hydraulic master cylinder device, and FIG. 3 is a front view of the hydraulic master cylinder device.

  A hydraulic master cylinder device 1 for a front brake is attached to a handle bar 2 that steers a front wheel at the front of a vehicle body of a bar handle vehicle, and includes a hydraulic master cylinder 3 and an operation lever 4. The hydraulic master cylinder 3 is attached to the handlebar 2 by holding the vicinity of the grip 5 of the handlebar 2 with a mounting bracket 3b integrated with the cylinder body 3a and a holder 6, and fastening them with bolts 7. Yes. A pair of upper and lower lever brackets 3d, 3d provided with pivot mounting holes 3c, 3c project from the front side of the body of the cylinder body 3a. The operation lever 4 has a pivot base 4a between the lever brackets 3d, 3d. The shaft 8 is pivotally mounted using a collar 8 and a pivot 9.

  The cylinder body 3a has a cylinder hole 3e formed therein, and the piston 10 is inserted into the cylinder hole 3e so as to be movable. Further, a rotation restricting portion 3f for restricting the amount of rotation of the operation lever 4 from the bottom wall side of the cylinder body 3a toward the lever bracket 3d side is extended, and a brake lamp switch 11 is provided below the cylinder body 3a. Is attached. In addition, a cover portion 3g that covers an electrode connection hole forming portion 4h of the operation lever 4, which will be described later, is formed smoothly and continuously on the lever bracket 3d.

  The operation lever 4 includes a pivot base 4a that is pivotally mounted between the lever brackets 3d and 3d by the pivot 9, a grip operation section 4b that is disposed substantially along the front of the vehicle body of the grip 5, and a rotating lever. The rotating base 4a includes a working arm 4c (the operating portion of the present invention) that protrudes toward the handlebar side of the moving base 4a, and a protruding portion 4d that protrudes from the lower surface of the rotating base 4a to the anti-grip operating portion 4b. Is provided with a pivot insertion hole 4e. The projecting portion 4d includes a pushing portion 4f that pushes the actuator of the brake lamp switch 11, a stopper portion 4g that abuts on the rotation restricting portion 3f, and an electrode connection hole forming portion 4h. An electrode connection hole 4i for connecting an electrode for electroplating the operation lever 4 is formed on the end surface of the electrode gripping hole forming portion 4h on the counter gripping operation portion 4b side.

  The electrode connection hole 4i is a female screw hole for screwing an electrode having a male screw part at the tip, and a large-diameter recess 4j is continuously formed on the opening side of the electrode connection hole 4i. Further, the electrode connection hole 4i is formed so that the opening portion faces downward in a state where the vehicle on which the operation lever 4 is mounted is parked.

  The operating lever 4 is subjected to a plating process after masking the pivot insertion hole 4e requiring dimensional accuracy. The plating process is performed by a well-known method, and a plurality of operation levers 4 in a state in which an electrode having a male screw part at the tip is screwed into the electrode connection hole 4i are placed on the plating jig with the gripping operation part 4b facing downward. When suspended and immersed in a plating solution and energized, a metal such as chromium is deposited on the surface of the operating lever 4 to form a plating layer. The plated layer is applied to the entire surface of the operation lever 4 including the large-diameter concave portion 4j other than the pivot insertion hole 4e and the electrode connection hole 4i subjected to masking.

  In the operation lever 4 formed in this way, the pivot base 4a is inserted between the lever brackets 3d and 3d, the pivot mounting holes 3c and 3c and the pivot insertion hole 4e are aligned, and the collar 8 and the pivot 9 are connected. By inserting, it is in a state of being pivotally mounted around the pivot 9. A resilient force of a return spring (not shown) disposed in the cylinder hole is always applied to the operation lever 4 mounted on the hydraulic master cylinder 3 through the piston 10 so that the operation lever 4 is not operated. The position is set by contact between the stopper portion 4g and the rotation restricting portion 3f of the cylinder body 3a, and a predetermined grip margin is formed between the grip operation portion 4b of the operation lever 4 and the grip 5.

  In the operation lever 4 described above, since the plating is performed after masking the pivot insertion hole 4e requiring dimensional accuracy, the aesthetic appearance is improved without reducing the operation feeling of the operation lever 4, and the rust is prevented. Can be achieved. Further, since the electrode connection hole 4i is hidden by the cover 3g when the operation lever 4 is not operated, the electrode connection hole 4i is not visible from the outside without being subjected to plating treatment. The aesthetics are not spoiled by. In particular, the large-diameter recess 4j formed on the opening side of the electrode connection hole 4i is plated, and the electrode trace is located on the bottom side of the large-diameter recess 4j. It can prevent deteriorating the aesthetics. Further, since the cover portion 3g is formed smoothly and continuously on the lever bracket 3d, the appearance is good and the aesthetic appearance is improved.

  Furthermore, since the electrode connection holes 4i are formed in the electrode connection hole forming portion 4h which is the end surface in the longitudinal direction of the operation lever 4, a plurality of operation levers 4 are suspended from the plating jig with the longitudinal direction facing up and down. Thus, it is possible to immerse in the plating solution, so that many operation levers can be immersed in the plating solution at a time, and the plating process can be performed efficiently. Further, since the electrode connection hole 4i is formed so that the opening portion faces downward in a state where the vehicle on which the operation lever 4 is mounted is parked, it is difficult for foreign matter to enter the electrode connection hole 4i. Even if it enters, it can be discharged well.

  The present invention is not limited to the brake operation lever as in the above-described embodiment, but can be applied to the clutch operation lever, and is not limited to the master cylinder operation lever. The present invention can also be applied to an operation lever that pulls a connecting means that is connected to a brake device such as a wire. Further, the electrode connection hole may be formed at any position except the pivot insertion hole, the working arm, and the portion exposed to the outside in a non-operating state. For example, the rotation restricting portion covered by the cover portion It can also be provided on the contact surface side. Further, the electrode connection hole may be an insertion hole in which a banana plug provided at the tip of the electrode can be fitted without providing the female screw portion, and a sealing member (for example, a plug body or the like) is formed in the opening of the electrode connection hole. , Sticking seal, resin injection) can be attached to make the electrode traces less noticeable.

  Furthermore, in the above-described embodiment, as shown in FIGS. 1 and 2, the electrode connection hole is formed obliquely downward and opened downward, but the present invention is not limited to this, and the electrode connection hole is What is necessary is just to form in the direction which discharges | emits foreign matters, such as water and dust which penetrate | invaded in the hole, according to the attitude | position at the time of parking of the vehicle which mounts a hydraulic master cylinder apparatus. Further, the present invention can also be applied to an operation lever that is applied to a vertically placed hydraulic master cylinder device. Furthermore, the cover portion is not limited to being integrally formed with the lever bracket, and may have a structure in which another component is mounted.

It is II sectional drawing of FIG. It is a side view of a hydraulic master cylinder device showing an example of the present invention. It is a front view of a hydraulic master cylinder device similarly.
