BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopper device for a brake master cylinder in a four-wheeled vehicle.

[0002]

2. Description of the Related Art A brake master cylinder that interlocks with a brake pedal is provided in the engine room of a four-wheeled vehicle. When the brake pedal is depressed, the brake master cylinder has its mounting surface. Due to lack of rigidity, etc., it will move about 5 to 10 mm to the front side (the brake pedal will escape by that amount), resulting in a time loss in the braking time of the car and adversely affecting the braking force. When the brake pedal is depressed, the driver feels a sponge and the brake feeling is not good.

The present invention has been made in view of the above conventional problems, and an object thereof is to prevent the protrusion of the brake master cylinder to reduce the braking time, thereby reducing the braking force. It is an object of the present invention to provide a stopper member for a brake master cylinder that can be transmitted more accurately to improve safety, and that provides an excellent brake feeling with a "click" when the brake pedal is depressed.

[0004]

To this end, the present invention has a mounting portion having a mounting hole for a mounted body in an engine room, and a block portion integrally connected to the mounting portion. The structure is provided with a stopper body and a stopper protrusion that is provided on a surface facing the moving direction of the brake master cylinder in the block portion and that prevents the brake master cylinder from moving to the front side when the brake pedal is depressed. It is what

[0005]

The stopper device having the above-mentioned structure is provided with a member close to the brake master cylinder in the engine room of a four-wheeled vehicle, preferably on the outer surface of the strut house, by bolting to the mounting hole of the mounting portion, and if necessary. When the attachment is carried out through the attached attachment stay which is also used for this, the stopper protrusion and the brake master cylinder are firmly attached in such a state that they are in contact with each other. In this state, even if the brake petal is stepped on and the brake master cylinder tries to move (protrude) to the front side with this,
The brake master cylinder is pressed by the pressing surface of the stopper protrusion and is prevented from moving (protruding).

EXAMPLES Examples will be described below with reference to the drawings. FIG. 1 is an overall perspective view, FIG. 2 is a perspective view seen from the above two directions, and FIG. FIG. 4 is an enlarged cross-sectional view showing the mounting state, FIG. 4 is an exploded perspective view showing the mounting state, FIG. 5 is a schematic view of the used state, and FIG. 6 is an explanatory view of the used state. In these figures, the stopper body 10 is preferably aluminum. The stopper body 10 is an integrally formed product made of a light metal material such as, and has a vertically long quadrangular mounting portion 11 having two vertically long bolt holes 12 with respect to a mounted body (strut house) A in the engine room, and the mounting portion 1.
1 has a block portion 13 continuously provided in a substantially L shape,
Two cylindrical stopper protrusions 14 are provided on the surface 1 of the block portion 13 on the same axis as the moving (protruding) direction of the brake master cylinder B in the block portion 13.
It is projected so that it can move back and forth from 5. More specifically, the two cylindrical stopper protrusions 14 are preferably a light metal material such as aluminum, and these stopper protrusions 14 are movably inserted into the insertion holes 16 of the block portion 13 and A small-diameter screw hole 17 communicating with the hole 16 and a slightly large-diameter adjustment bolt insertion hole 18 are integrally connected to the inserted adjustment bolt 19, and the adjustment bolt 19 is screwed into the screw hole 17 by forward and reverse rotation. The stopper protrusion 14 is integrated with the adjusting bolt 19 so as to be able to advance and retreat from the block surface 15 through the insertion hole 16, and the forward rotation (or reverse rotation) operation of the adjusting bolt 19 and the brake master cylinder B and the respective units. The gap with the stopper protrusion 14 can be finely adjusted. Then, this adjusted state is held by fixing the screw portion of the adjusting bolt by screwing each set screw 21 into each vertical hole 20 orthogonal to each screw hole 17. In FIG. 1, two holes 2 are provided in the inclined surface portion of the block portion 13.
Reference numeral 2 denotes a mounting bolt hole of the attached mounting stay 23.

In this embodiment, two stopper protrusions 14 are provided, but the number of stopper protrusions 14 is not limited to this. Further, in the present embodiment, the gap of the stopper protrusion 14 with respect to the brake master cylinder B is shown by the rotating operation of the adjusting bolt 19, but the gap adjustment with respect to the brake master cylinder B is as shown in FIG. , Fix the stopper protrusion 14 (or the stopper body 1
No. 0 block portion 13) and the mounting bottle hole 12 in the mounting portion 11 is a horizontally long hole, and when the stopper tool is mounted on the mounted body (strut house) A, the whole body can be mounted in either the left or right direction (horizontal direction). (Direction) to adjust the gap and attach.

The stopper device of the present invention constructed as described above, as shown in FIG. 4 and FIG.
After fixing the attached mounting stay 23 to the block portion 13 of the stopper body 10 by screwing the bolts 24 into the mounting bolt holes 22, this is attached to the outer surface of the strut house A in the engine room of the four-wheeled vehicle.
The bolt 25 is screwed into the mounting hole of the strut house A via 2 and the bolt 26 is screwed into the mounting hole of the strut house A through the bolt hole 27 of the mounting stay 23, and then, firmly attached. The stopper protrusions 14 are moved by rotating the adjusting bolts 19 so that the stopper protrusions 14 are adjusted to such an extent that the gap with the brake master cylinder B comes into contact with the stopper protrusions 1.
The position of No. 4 is fixedly held by screwing each set screw 21 into each hole 20. In the case of the embodiment shown in FIG. 7, the horizontally elongated hole 12 of the mounting portion 11 of the stopper body 10 moves the screwing position of the bolt 25 in the left-right direction so that the stopper protrusion 14 and the brake master cylinder B are connected to each other. Are adjusted so that the gaps of the two contact with each other.

In the four-wheeled vehicle equipped with the stopper device of the present invention, even if the brake master cylinder B is moved (protruded) to the front side with the depression of the brake petal, the brake master cylinder B is moved to the fifth position. As shown in FIGS. 6 and 6, the stopper protrusion 14 is pressed by the surface of the stopper protrusion 14 to prevent movement (protrusion).

[0010]

As described above, according to the present invention,
The movement (protrusion) of the brake master cylinder to the front side when the brake pedal is stepped on is reliably prevented, so the braking time is shortened, the braking force is transmitted more accurately, and the safety is improved. When you step on the brake petal, you will get a "clicky" outstanding brake feeling without feeling spongy.
