The pressure oil is guided by the brake hose 00 connected to the hydraulic master turn 1) and the pressure oil suction valve device 50 VC is connected to the hydraulic master turn 1]. It looks like he will be introduced to the ring room. The pressure oil suction valve system @50 has a function of sucking back a certain amount of pressure 411 from the cylinder chamber at the end of braking. It should be noted that the pressure oil suction valve device 50Q is connected to the bleed hole 38 in the cylinder chamber 51, so that gas can escape easily in the cylinder chamber 51.

In addition, the platform member 15vC has a boat P of different diameters formed therein, and the orifice part IN'157a1' is rotated by operating the lever 16 in advance to obtain the desired diameter σ) boat. By matching the boat P1 of the piston 13, it is possible to change the Mt Wy lid resistance and obtain the desired CG anti-nose dive performance. That is, if the main communication oil passage M is blocked λ', Q
When the buffer oil flows from the chamber to the R chamber, the flow path resistance increases and the contraction of the front fork 10' is restricted.

As an example of unfaithfulness, the construction is as follows: during braking, pressure oil is discharged from the hydraulic master turn cylinder. The pad member 30 moves forward against the force of the plate spring 37U and the resilient force, and the friction pad member 30 follows its pressing head path α.
The disk plate DIC slides along the hanger bin 29 and rotates in the direction of the τ arrow, and due to the reaction force,

■At the same time as the braking is finished, the sliding bin 4 is moved by the elastic restoring force of the vibration-absorbing rubber 8vr, and the bolt 24 A is tilted on the opposite side of the shaft, and the bolt 24 A is moved backward.
The piston 13 also moves back due to the compression coil 7 pulling S (/I bullet reciprocating force vc).Thus, the main communication oil passage M becomes conductive.
The anti-nose dive mechanism 12 becomes inactive.

Therefore, in the non-embodiment, the upper and lower protrusions 1 and 2.3 of the front fork 1 are attached.

The room for this to occur is reduced in terms of OJ and 2. In addition, by connecting the sliding bin 40) to the body 21, the rigidity of the sliding bin 40) is improved compared to the conventional UI cantilever type, and the sliding against the upper protruding piece 2 is improved. The upper protruding piece 2σ between the two forces should be passed through the sliding bottle with as little clearance as possible with respect to the opening, and there may be "rattleness" due to running vibrations, or ) Haho7' ” When 21 slides and displaces θ)“
There is little rattling ~ Even if the boots are fitted with an external fitting type (not located on the sliding surface), there is no problem with the external fitting.And,
When installed with the boot external fitting type, the frictional resistance on the sliding surface σ is reduced by 71S compared to the internal fitting type (type where the end of the boot is inserted into the sliding surface).
21 change (32 is easy to perform 2"L, braking characteristics are improved.

Moreover, in the case of non-operation, the brake force is too much for the body 2.

Compared to VC, the center of gravity of the rear 20 is far away from the point of load application, so the above functional ability cannot be fully demonstrated.
Regardless of whether it is in operation or not, the Kimaria 20 is maintained in the correct posture, so that so-called dragging, uneven adhesion, etc. of the friction pad 31 are effectively prevented. Note that the sliding bottle 4 and the sliding bottle shaft 5 are arranged approximately point symmetrically from the center position to the load application point vc K=J'.
Therefore, even at this point α), the posture is maintained correctly (δ2').

Furthermore, when braking, the braking force U) acting on the cylinder f-21, vc, the sliding pin 4 is used as the fulcrum of the cylinder (body 21 tilting) to obtain a moment. Also, the anti-/- dive mechanism 12 can be activated.

It goes without saying that the invention can also be applied to a front end that does not have an anti-nose dive mechanism.

Hereinafter, as is clear from the explanation of the implementation column σ), in the floating Kimaria type disc brake device, a protruding piece is provided integrally with the front fork, and the threshold piece is provided with −K;
V+Sliding 1 part IF is supported, and the protruding piece VC is formed in the gear rear body, and the T bifurcated part straddles the protruding piece. By passing the protrusion 14' through the VC and fixing it to the bifurcated part (1), the Kimaripa S is always held in the correct posture, preventing uneven wear of the friction pad and the pulling and sliding phenomenon during braking. [Kicho Sua θ] Displacement swordsmith can easily do it without any difficulty. Attaching L, to the front fork;
Extra connecting bolts, etc. are also omitted, making the structure simpler and the weight lighter.
