Generally, when designing a new car, even if you try to install the booster main body 1 that is currently mass-produced, it will interfere with the surrounding components due to differences in the distance between the booster body 1 and the body panel 3 depending on the car model, making it difficult to obtain the optimal installation mode. An unexpected situation occurs. For this reason, in the conventional mounting structure for a booster, the booster main body 1 is attached to the threaded portion 2 of the tie rod 2, as shown in FIG.
When attached to the vehicle body panel 3 by screwing the nut 7 into the a, the booster body 1 is formed by joining the front shell 1a and the rear shell 1b, and the vehicle body panel 3.
A spacer 4 having a size sufficient to avoid the above-mentioned interference was interposed between them. In this case, in order to prevent water from entering from the engine compartment side E to the driver's seat side D, gaskets 6 are sandwiched between the booster body 1 and the spacer 4 and between the spacer 4 and the vehicle body panel 3. Ta. As shown in FIG. 4, the rear shell 1b has a flat portion 1b1 at the center, an inclined portion 1b2 at the outer periphery, and bulges out in the direction of the panel 3 as a whole. The flat portion 1b1 is fixed to the vehicle body panel via the tie rod 2. The internal space of the main body 1 consisting of the rear shell 1b and the front shell 1a is divided into a first working chamber A that communicates with a negative pressure source and a second working chamber that communicates with the atmosphere by a diaphragm (not shown). Working chamber B
It is defined as.

However, according to the conventional booster, by switching the second working chamber B to negative pressure and atmospheric pressure, the fourth
As shown in the figure, the stresses l and m with the boundary 1b3 between the sloped part 1b2 and the flat part 1b1 as a fulcrum are applied to the sloped part 1b2.
This causes shell deformation. Therefore, as disclosed in Japanese Patent Publication No. 60-561, a reinforcing ring 72 is provided inside the flat part 1b1 , and its outer edge part 76 is brought into contact with the inner surface of the inclined part 1b2 . was effective only against the stress l, and could not prevent the deformation of the inclined portion 1b2 due to the stress m.

Therefore, the present invention provides an inclined portion 1b 2 of the rear shell on the outer periphery of the spacer 4 provided corresponding to the flat portion 1.
A rigid extending portion 4f is formed to prevent bulging deformation of the inclined portion 1b2, thereby preventing outward deformation of the inclined portion 1b2 .

るように構成されている。 The mounting structure of the booster according to the present invention is constructed as follows. That is, as shown in FIGS. 1 and 2, the threaded portion 2a of each tie rod 2 that penetrates the booster main body 1 and is disposed on the rear extension tube 1a side of the main body 1 has this threaded portion. A spacer 4 having a hole 4a penetrated at each position corresponding to the spacer 2a,
Each tie rod 2, which is interposed between the booster main body 1 and the vehicle body panel 3 and protrudes from the booster main body 1, is inserted outside the vehicle body panel 3 through the hole 4a of the spacer 4 and the mounting hole 3a of the vehicle body panel 3. In the mounting structure of the booster which is screwed in place, a series of ring-shaped grooves 4b surrounding each tie rod 2 are provided in the surface of the spacer 4 facing the booster main body 1 in the circumferential direction. And this groove 4
An O-ring-shaped sealing member 5 is housed in the groove 4b with a portion thereof exposed outside the groove 4b. In the spacer 4 according to this embodiment, the sealing member 5 surface is brought into close contact with the outside of the booster main body 1 so that each hole 4a is fitted into the threaded portion 2a of the tie rod 2 at each position described above. At the outer surface of the spacer 4, a gasket 6 formed on a disc surface is inserted into the threaded portion 2a of the tie rod 2 through the hole 6a at each position, which is concentrically penetrated through each hole 4a of the spacer 4. The surfaces are concentrically mated with a mating fit. In this way, the groove 4b on the inner surface
The booster main body 1 has a spacer 4 on the rear extension tube 1a side, in which a seal member 5 is housed and a gasket 6 is closely arranged on the outer surface.
When attached to the vehicle body panel 3, the sealing member 5 described above is configured to seal between the spacer 4 and the booster main body 1.

る。 Next, the action will be explained. When attaching the booster body 1 having the above structure to the vehicle body panel 3, each tie rod 2 is attached to the surface of the vehicle body panel 3 in advance.
Since the mounting holes 3a are provided through the mounting holes 3a at respective positions corresponding to the arrangement of the After penetrating into the mounting holes 3a provided at each position, the booster main body 1 is easily and securely attached to the vehicle body panel 3 by screwing and tightening the nuts 7 onto the outwardly protruding screw portions 2a. Can be installed on. At this time, the spacer 4 on the booster main body 1 side is
The rigid spacer 4 is reliably sealed by the O-ring-shaped sealing member 5 that is fitted into the ring-shaped groove 4b without the tightening force of the tie rod 2 acting thereon, and the axial dimension of the rigid spacer 4 does not deteriorate over time. Therefore, even after long-term use, the original state of attachment to the booster main body 1 can be maintained. Even if the inclined portion 1b2 attempts to deform due to the stress m, the rigid extending portion 4f receives the pressure and blocks this deformation. Since the stress m is considered to be larger than the stress l, it is better to provide the extending portion 4f.
It can be said that it is highly effective in preventing shell deformation.

As explained above, according to the present invention, a rigid extension part is formed on the outer periphery of the spacer provided on the flat part of the rear shell constituting the main body of the booster to prevent the bulging deformation of the inclined part of the rear shell. Therefore, deformation of the inclined portion can be prevented, durability can be improved, and deterioration of braking caused by changes in volume inside the shell can be prevented.
