[0027]
FIG. 6 shows the non-operating state of the front wheel brake Bf and the rear wheel brake Br. The spring retainer 19 has stopper pieces 31 and 31 under the restriction holes 32 and 32 of the equalizer case 15 due to the set load of the delay spring 20. The joint member 18 is positioned at the lower limit that is received by the bottom wall of the equalizer case 15, and the equalizer lever 17 has its first end portion 17 ₁ at the bottom wall of the equalizer case 15. And the connecting shaft 23b of the second end portion 17 ₂ is brought into contact with the upper end surface of the second long hole 27 ₂ . On the other hand, the first elongate hole 27 ₁ is located ascent limit the second input cable 24 _{and second} connection terminals 29 comes into contact with the upper end face of the long hole 27 _1.
[0028]
Now, when the interlocking brake lever 10 ₁ is operated to pull the first input cable 24 ₁ and pull up the central portion of the equalizer lever 17, the connecting shaft 23b of the second end portion 17 ₂ of the equalizer lever 17 is initially Since the set load of the delay spring 20 holds the lower limit via the spring retainer 19, first, the equalizer lever 17 swings upward with the connecting shaft 23b as a fulcrum as shown in FIG. leading the cable 25 _1, thereby the rear wheel brake Br is first operated. By increasing the operation force of the interlock brake lever 10 _1, the first input cable 24 ₁ traction exceeds a set load of the delay spring 20, as shown in FIG. 8, now the overall equalizer lever 17 is raised, with further pulling the first output cable 25 _1, the connecting shaft 23b compresses the rise Shitsusu delay spring 20 with the spring retainer 19, by pushing up the joint member 18 at the upper end surface of the second elongated hole 27 ₂ Since the second output cable 25 ₂ is pulled, the front wheel brake Bf is actuated. In this way, delaying the operation timing of the front wheel brake Bf from the rear wheel brake Br is effective in obtaining a good braking feeling of the motorcycle 1.
[0029]
When the second end portion 17 ₂ of the equalizer lever 17, that is, the connecting shaft 23 b rises to a predetermined position, the stopper pieces 31, 31 of the spring retainer 19 that moves with the second end 17 ₂ are received by the upper end surfaces of the regulation holes 32, 32 of the equalizer case 15. And further rise is prevented. As a result, an increase in the traction force of the second output cable 25 ₂ is suppressed at that time, and the braking force of the front wheel brake Bf can be kept constant.
[0030]
Subsequently, when the first input cable 24 ₁ traction further increased, the equalizer lever 17 is swung upwards as a fulcrum a connecting shaft 23b of the stopped state again, to be further pulling only the first output cable 25 ₁ Therefore, the braking force of the rear wheel brake Br is further increased.

It is avoided that the second input cable 24 ₂ and the independent brake lever 10 ₂ are moved unnecessarily from the joint member 18 side by lowering in the first long hole 27 ₁ , that is, by the action of the first lost motion mechanism 33 _1. The
[0032]
Again, return to the non-operating state of the front wheel brake Bf and the rear wheel brake Br is shown in FIG. 6, now operates the independent brake lever 10 _2, when pulling the second input cable 24 _2, as shown in FIG. 10, Since the connection terminal 29 of the second input cable 24 ₂ pulls up the joint member 18 at the upper end surface of the first elongated hole 27 ₁ , the second output cable 25 ₂ is pulled by the joint member 18 to operate the front wheel brake Bf. Can do.
[0033]
In this case, the connecting shaft 23b engaged with the second long hole 27 ₂ of the joint member 18 is relatively lowered in the second long hole 27 _{2 as} the joint member 18 is raised, that is, the second By the action of the lost motion mechanism 33 ₂ , it is possible to avoid giving unnecessary movement to the equalizer lever 17 and the first input cable 24 ₁ from the joint member 18 side.
[0034]
Further, by operation of the interlock brake lever 10 _1, while being interlocked actuating the rear wheel brake Br and the front wheel brake Bf, by operating the independent brake lever 10 _2, if towing a second input cable 24 _2, even remain in the second end portion 17 ₂ is increased limit of the equalizer lever 17 stopper piece 31 of the spring retainer 19 abuts against the upper end surface of the restricting holes 32 and 32 of the equalizer case 15, a second input cable 24 _{Since the second} traction force is applied to the second output cable 25 ₂ via the joint member 18, the braking force of the front wheel brake Bf can be further increased.
[0035]
By the way, the first input cable 24 _{1 and} the second input cable 24 ₂ respectively connected to the interlocking brake lever 10 ₁ and the independent brake lever 10 ₂ penetrate the ceiling wall of the equalizer case 15 and are respectively connected to the equalizer lever 17 and the joint member 18. The first output cable 25 ₁ and the second output cable 25 ₂ that are connected to the rear wheel brake Br and the front wheel brake Bf pass through the bottom wall of the equalizer case 15 and are connected to the equalizer lever 17 and the joint member 18, respectively. Therefore, all the cables 24 ₁ , 24 ₂ , 25 ₁ , 25 ₂ do not have an extreme bent portion such as a U-shape, and therefore, the operation force can be efficiently transmitted between the cables. The brake operation can be lightened.
[0036]
In particular, since the second input cable 24 ₂ and the second output cable 25 ₂ are coaxially connected via the joint member 18, the operation force is transmitted between the second input and output cables 24 ₂ , 25 _2. This can be performed more efficiently, and the front wheel brake Bf can be operated more lightly.
[0037]
The fact that all the cables 24 ₁ , 24 ₂ , 25 ₁ , 25 ₂ do not have a large bent portion facilitates the routing work and reduces the steering resistance by all the cables 24 ₁ , 24 ₂ , 25 ₁ , 25 _2. Also brings.
[0038]
The present invention is not limited to the above embodiments, and various design changes can be made without departing from the scope of the invention.
[0039]

Also, the first output cable and the second output cable connected to the motorcycle rear wheel brake and front wheel brake operating levers are connected to the equalizer. because through the case bottom wall of each connected to both ends of the equalizer lever, entrance, without the presence of extreme bends, such as U-shape to an output cable, input, operating force between the output cable transmitting conducted efficiently, and can be lightly brake operation, also enter large the bent portion does not exist in the output cable More, it is possible to reduce the steering resistance by facilitating the cable arrangement work.
[0040]
To or within Lee co riser casing accommodates a joint member for connecting the one end and a second output cable equalizer lever, a second input connected to separate brake lever that is pivotally supported to the other end of the steering wheel cables, since the connected coaxially to the second output cable through the joint member penetrates the ceiling wall of the equalizer case, it is possible to independently operate the front wheel brake by operating the independent brake lever, when the second Since the input cable and the second output cable are coaxially connected via the joint member, it is possible to more efficiently transmit the operation force between the two cables and to operate the front wheel brake more easily. it can. Also, if the independent brake lever is operated while the rear brake and front wheel brake are interlocked by operating the interlock brake lever, the operating force is applied only to the second output cable, and the braking force of the front wheel brake is increased. Can be enhanced.
[0041]
Furthermore, when operating the interlocking brake lever, it is possible to avoid unnecessary movement from the joint member side to the second input cable and the independent brake lever by the action of the first lost motion mechanism provided between the second input cable and the joint member. In addition, when the independent brake lever is operated, the second lost motion mechanism provided between the equalizer lever and the joint member avoids unnecessary movement from the joint member side to the equalizer lever. The mutual interference of the independent brake levers can be prevented and the operation feeling can be improved.
[0042]
