The function and effect of the present invention can be exemplified by, for example, a silicone gel which has been adjusted to a gel state by suppressing the degree of crosslinking of silicone rubber to a low level, as a gel substance for shock absorption. This is impregnated with unreacted liquid silicone oil, has low propagation of vibration waves, and is widely used as a buffer material.

Incidentally, as one of the gel materials for shock absorption, there is a product commercially available from Bridgestone Corporation under the name of MNCS (rebound resilience 25% or less). However, this is only an example, and other gel-like substances for shock absorption can be used.

When the object to be supported, such as a bathtub body, a waterproof pan and a pump, is supported by using the vibration-proof support member of the present invention, the elastic action of the elastic body and the shock absorbing gel body are excellent. Vibrations from the supported body can be favorably absorbed based on the buffering action, and the vibrations from these can be suppressed from being transmitted to an installation surface such as a floor slab or a ceiling or a wall below the floor. Accordingly, the noise level can be effectively reduced.

The present invention is characterized in that a rigid plate made of a material different from the elastic body and the shock absorbing gel body is provided on the elastic body. In this case, the deformation of the anti-vibration support member when a load is applied to the anti-vibration support member including the elastic body and the shock absorbing gel body can be satisfactorily suppressed by the rigid plate.

Therefore, even when the legs and the like of the bathtub main body are mounted and fixed on the vibration isolating support member via the mortar, it is possible to prevent the mortar from breaking due to deformation of the vibration isolating supporting member. Therefore, it is possible to sufficiently prevent sinking and rattling of a supported body, for example, a bathtub main body due to cracks in the mortar, and prevent insufficient installation of the bathtub.

Specifically, the diameter of the support portion with respect to the supported portion can be increased. In this case, a slight displacement of the supported portion in the horizontal direction when the supported body is installed can be absorbed, and the work of installing the supported body is facilitated.

Further, since the rigidity of the vibration-damping support member can be increased, the shock absorbing gel body can be attached to the elastic body in a state of being divided into a plurality of parts, and the amount of expensive shock absorbing gel body used can be reduced. Thus, an advantage that cost can be reduced is obtained.

According to a second aspect of the present invention, a rubber elastic body is used as the elastic body. According to the present invention, the elastic body can be provided with sufficient elasticity and the durability life can be increased. It can be good.

According to a fourth aspect of the present invention, the elastic body is provided with a downwardly-recessed receiving chamber including a support portion and a peripheral wall portion that falls from the peripheral edge of the support portion, and the shock absorbing gel body is stored therein. According to the present invention, it is possible to favorably suppress the deformation of the shock-absorbing gel body having a low pressure resistance,
Also, there is an advantage that the shock absorbing gel body can be easily incorporated into the elastic body.

According to a fifth aspect of the present invention, in the fourth aspect of the present invention, the shock absorbing gel body is protruded below the accommodation chamber, and is independently grounded on the installation surface. For example, since the elastic body does not come into contact with the installation surface, it is possible to prevent the vibration from being transmitted to the installation surface via the elastic body, thereby obtaining an advantage that the vibration-proof effect can be enhanced.

According to a sixth aspect of the present invention, an iron plate is used as the rigid plate. In the case of this iron plate, since the rigidity is high, the deformation of the vibration isolating support member can be more effectively suppressed, and the rigidity can be reduced. The thickness of the plate can be reduced.

According to a seventh aspect of the present invention, the rigid plate is provided embedded in the elastic body. According to the present invention, it is possible to prevent the rigid plate from being exposed to the outside and impairing the appearance. it can. Further, in the present invention, particularly when an iron plate is used as the rigid plate, it is possible to eliminate the need for the iron plate to be subjected to a rust prevention treatment such as galvanization and to prevent the generation of rust semipermanently. In particular, when an iron plate is used as the rigid plate, the rigidity of the iron plate is high, so that the thickness of the anti-vibration support member, specifically, the embedded portion of the rigid plate in the elastic body can be reduced. Benefits are obtained.

The invention according to claim 8 relates to a method of manufacturing a vibration-proof support member, wherein a support pin is projected into a molding cavity formed between a first mold and a second mold which can be divided from each other. Then, the through holes formed in the rigid plate are fitted to the support pins, and the rigid plate is supported in a floating state at the intermediate portion of the molding cavity. In this state, the rubber material is injected into the molding cavity and molded. According to the present invention, the rigid plate can be easily provided in the rubber elastic body in an embedded state.

According to a ninth aspect of the present invention, when the rubber elastic body is molded, the rigid plate is provided with a through-hole separate from the through-hole for supporting by the support pin, and the through-hole is provided on both sides of the rigid plate. According to the present invention, the rigid plate embedded in the rubber elastic body can be satisfactorily integrated with the rubber elastic body according to the present invention. It is possible to satisfactorily prevent the rigid plate from breaking through the rubber elastic body and protruding outside.

When a rigid plate made of an iron plate is embedded inside the rubber elastic body, a rubber-based adhesive is applied to the surface of the rigid plate, and baking is performed. It is preferable because the adhesiveness with the polymer can be made good.
