In order to make the connection, a considerably long interlocking brake wire is required, and since the wiring is formed with many bent portions, the transmission efficiency of the operating force is reduced, which is not preferable.

る。To achieve the above object, the present invention provides a brake lever for operating a front wheel brake on a steering wheel, while a brake pedal for operating a rear wheel brake. A master cylinder capable of hydraulically operating the front wheel brake is mounted on a vehicle body below a steering wheel, and can be pushed to the outer end of a piston of the master cylinder in a vehicle brake device in which the vehicle is pivotally supported at a lower part of the vehicle body. In this manner, a knocker pivotally supported by the master cylinder is brought into contact with the master cylinder, and the knocker is pivotally supported by the master cylinder so that the piston can be pushed through the knocker. 1 actuation lever and 2nd
The first feature is that the operating levers are separated from each other, and a brake lever and a brake pedal are connected to the first operating lever and the second operating lever via a front brake wire and an interlocking brake wire, respectively. .

ることができる。According to the first feature, when only the brake lever 2 is operated, the first operating lever pushes the piston of the master cylinder via the knocker, and the front wheel brake is actuated by the hydraulic pressure generated accordingly. Can operate. During this time, since the knocker is separated from the contact portion with the second operation lever, the operation force of the brake lever is not transmitted to the brake pedal, and the inoperative state of the rear wheel brake can be maintained.

ダルの操作力は伝達されない。When only the brake pedal is operated, the rear wheel brake is actuated, and at the same time, the second operating lever is swung through the interlocking brake wire to push the piston of the master cylinder through the knocker. The front wheel brake can also be operated by the hydraulic pressure generated accordingly. During this time, the knocker is separated from the contact portion with the first operating lever, so that the operating force of the brake pedal is not transmitted to the brake lever.

ｆを作動することができる。Therefore, if only the brake lever 2 is operated, as shown in FIG. 5, the first operating lever 32 is pulled up with the knocker 31 via the front brake wire 4 and swings upward around the pivot 34. Therefore, the knocker 31 pushes the piston 23 of the master cylinder 20 upward to generate hydraulic pressure in the hydraulic chamber 22. The hydraulic pressure is supplied from the output port 27 through the hydraulic conduit 28 to the front wheel brake Bf.
To the front wheel brake B
f can be activated.

Ｂｒの非作動状態は維持される。During this time, the contact piece 31a of the knocker 31 swings so as to escape from the contact surface 33a of the second operation lever 33 toward the arc surface 33b, so that the second operation lever 33 is left behind. . Therefore, the second operating lever 3
3, the interlocking brake wire 6 and the brake pedal 3
The operation force of the brake lever 2 is not transmitted, and the inoperative state of the rear wheel brake Br is maintained.

で，後輪ブレーキＢｒを作動することができる。Next, if only the brake pedal 3 is operated,
The operating force is distributed to the rear brake wire 5 and the interlocking brake wire 6 via the equalizer 40 as traction force. The traction force distributed to the rear brake wire 5 acts on the operating lever 7 and swings it in the operating direction, so that the rear wheel brake Br can be operated.

る。On the other hand, the traction force distributed to the interlocking brake wire 6 acts on the second operating lever 33 and applies it to the pivot 3.
4, the contact surface 33 a of the second operating lever 33 is pressed against the contact piece 31 a of the knocker 31, and the master cylinder 20 is moved with the knocker 31.
Of the piston 23, the swing torque of the second operating lever 33 increases the return spring 2 of the piston 23.
When the value of the return torque exerted on the knocker 31 is smaller than that of the knocker 31, the piston 23 remains at the retreat limit. When the swing torque exceeds the return torque by the return spring 24, the second operating lever 33 swings rearward with the knocker 31, as shown in FIG.
3 is pushed upward, and the front wheel brake Bf can be operated with the hydraulic pressure generated in the hydraulic chamber 22.

A knocker 31, a first operating lever 32 and a second operating lever 33 are pivotally supported by a lever holder 30 provided continuously with the brake lever 2, and the brake lever 2 and the first operating lever 32 are connected via a front brake wire 4. The brake pedal 3 and the second operating lever 33 are connected via the interlocking brake wire 6, and the interlocking brake wire 6 is arranged along one side surface of the main frame 8. With the shortest length, it can be easily arranged on one side of the main frame 8,
Not only can interference with other objects be avoided, but also lowering of the transmission efficiency of the operating force can be suppressed as a routing with less bending.

ない。As described above, according to the first aspect of the present invention, the brake lever for operating the front wheel brake is pivotally supported on the steering wheel, while the brake pedal for operating the rear wheel brake is operated. In a vehicle brake device pivotally supported at a lower portion of a vehicle body, a master cylinder capable of hydraulically operating a front wheel brake is mounted on a vehicle body below a steering handle so that the master cylinder can be pushed against an outer end of a piston of the master cylinder. A first rocker pivotally supported by the master cylinder so that the piston can be pushed through the knocker to the knocker. The operating lever and the second operating lever are brought into contact with each other so as to be separated from each other.
Since the brake lever and the brake pedal are connected to the operating lever via the front brake wire and the interlocking brake wire, respectively, when only the brake lever 2 is operated, the first operating lever connects the piston of the master cylinder via the knocker. The front wheel brake can be actuated by the hydraulic pressure generated in response to the pushing, and during this time, the knocker separates from the contact portion with the second operating lever.
The operation force of the brake lever is not transmitted to the brake pedal.

ることができる。When only the brake pedal is operated, the rear wheel brake is operated, and at the same time, the second operating lever is rotated via the interlocking brake wire to push the piston of the master cylinder via the knocker. The front wheel brake can also be actuated by the hydraulic pressure generated accordingly, and during this time, the knocker moves away from the contact portion with the first operating lever, so that the operating force of the brake pedal is not transmitted to the brake lever. Thus, the inoperative state of the front wheel brake can be maintained.

操作力の伝達効率の低下を抑えることができる。Further, the interlocking brake wire is connected to the second operating lever pivotally supported by the vehicle body below the steering handle, so that the interlocking brake wire can be made relatively short and bent. It is possible to suppress a decrease in the transmission efficiency of the operation force as a routing with a small number of wires.
