  When the rear wheel brake operation element 5 is braked, in the initial input state, as shown in FIG. 6, the first brake wire 17 is pulled and the equalizer lever pulling portion 23c is pulled. At this time, the spring force of the delay spring 31 is greater than the load applied to the second brake wire 18 (the spring force of the springs Rr1, Rr1, Rr2 in the rear wheel brake 3). The wire pulling portion 23a side turns to the second hydraulic master cylinder 19 side, the brake wire pulling portion 23a pulls the second brake wire 18, and the rear wheel brake 3 starts to operate. In this state, a traction force is generated in the direction in which the floating support shaft 27 is moved toward the one side portion 21c of the vehicle body mounting bracket 21. The floating support shaft 27 has a spring force of the delay spring 31 and a piston 19a. Since a force such as a return spring (not shown) in the second hydraulic master cylinder that urges toward the piston pushing portion 22c is acting, it floats until the traction force of the first brake wire 17 exceeds a predetermined value. The support shaft 27 is held, and the knocker 22 maintains the initial state.

  When the rear wheel brake operation element 5 is further braked from the initial input state and the traction force of the first brake wire 17 exceeds a predetermined value, the delay spring 31 extends and the equalizer lever 23 as shown in FIG. Is pulled to one side 21c side of the vehicle body mounting bracket 21, and the equalizer lever 23 balances the force acting on each of the brake wire pulling portion 23a side and the knocker connecting portion 23b (floating support shaft 27) side. It moves to the one side part 21c side of the vehicle body mounting bracket 21 while taking it. Along with this, the knocker 22 rotates about the fixed support shaft 28, and the piston pushing portion 22c pushes the piston 19a to start operating the front wheel brake 2, and the front wheel brake 2 is operated together with the rear wheel brake 3. Will be in the interlocked brake state.

  When the rear wheel brake operator 5 is further braked from the interlocked brake state, the equalizer lever 23 is further pulled as shown in FIG. 8, and the brake wire pulling portion 23a and the floating support shaft 27 are connected to the vehicle body mounting bracket. 21 is pulled to one side 21c side. Along with this, the knocker 22 rotates about the fixed support shaft 28 and pushes the piston 19a to brake the front wheel brake 2 together with the rear wheel brake 3, but the rotation restricting portion 22e and the rotation restricting member 29. , The rotation of the knocker 22 is restricted, the braking of the front wheel brake 2 is controlled, and the front wheel brake control state is established.

  If the rear wheel brake operation element 5 is further braked from the front wheel brake control state to the full stroke state, the knocker 22 has a rotation restricting portion 22e and a rotation restricting member 29 as shown in FIG. Since the rotation is restricted by contact and the floating support shaft 27 is held, the equalizer lever 23 has the brake wire pulling portion 23a that rotates around the floating support shaft 27 toward the second hydraulic master cylinder 19 side. The second brake wire 18 is pulled and only the rear wheel brake 3 is braked more strongly.

  In the present embodiment, as described above, the interlocking mechanism 6 is composed of three parts, that is, the second hydraulic master cylinder 19, the knocker 22, and the equalizer lever 23. Reduction can be achieved. Further, with the second hydraulic pressure master cylinder 19 attached to the vehicle body mounting bracket 21, the knocker 22, the equalizer lever 23, and the like from the back side of the vehicle body mounting bracket 21 using the opening 21h and the slit 21i of the vehicle body mounting bracket 21 The first brake wire 17 and the second brake wire 18 can be easily assembled, and the delay spring 31 has one end locked to the floating support shaft 27 and the other end fixed to the concave locking portion 21g. Since the delay spring 31 can be easily assembled, the delay spring 31 can be easily assembled, and the ease of assembly and the ease of maintenance can be improved.

  Furthermore, the processing cost of the vehicle body mounting bracket 21 can be reduced by forming the vehicle body mounting bracket 21 by casting and forming the concave locking portion 21g with a mold. In addition, the vehicle body mounting bracket 21 can be reduced in size and weight by providing the opening 21h and forming a trapezoidal shape with one side having a short side and the other side having a long side. Furthermore, since the plate-like portion 21b is formed in a concave shape that allows the equalizer lever 23 to rotate, the thickness of the vehicle body mounting bracket 21 can be suppressed while securing the rigidity. Further, by providing the vehicle body mounting bracket 21 with the rotation restricting member 29 that restricts the rotation of the knocker 22, the rear wheel brake 3 can be sufficiently operated while adjusting the operation of the front wheel brake 2.

  Further, the length of the delay spring 31, the length of the equalizer lever 23 from the equalizer lever pulling portion 23c to the brake wire pulling portion 23a, or the length from the equalizer lever pulling portion 23c to the knocker connecting portion 23b is changed. It can be applied to different car models.

  The present invention is not limited to the above-described embodiment, and the second hydraulic master cylinder, the knocker, and the equalizer lever may not be accommodated in the vehicle body mounting bracket. The hydraulic brake and the mechanical brake can be provided in reverse of the above-described embodiment, and the hydraulic brake may be two pots or more, and the type of the hydraulic brake or the mechanical brake is arbitrary.
