上記従来技術には、次の問題がある。すなわち、筒部３を連結部４を介して内 筒１に接続したために、径方向のバネ定数が低くなるとともに円周方向（捩り方 向）の剛性が低下し、これが当該防振ゴムの作動にとって不都合を来すことがあ る。例えば、当該防振ゴムによりモータの回転軸を支えると、その回転力により 内筒１が回転軸に従動しようとし、円周方向の剛性が低いために連結部４が回転 方向に大きく捩れて破断する虞がある。 The above conventional technology has the following problems. That is, the cylindrical portion 3 is inserted into the interior through the connecting portion 4. Because it is connected to the tube 1, the spring constant in the radial direction is low and the spring constant in the circumferential direction (torsion direction) is low. (direction) may decrease, which may cause problems for the operation of the vibration isolating rubber. Ru. For example, if the rotating shaft of the motor is supported by the anti-vibration rubber, its rotational force will cause The inner cylinder 1 tries to follow the rotating shaft, and the connecting part 4 rotates because the rigidity in the circumferential direction is low. There is a risk of it twisting significantly in the direction and breaking.

つぎに本考案の実施例を図面にしたがって説明すると、当該防振ゴムは、図１ に示すように、上記従来技術と同様に、内筒１と前記内筒１の外周側に配置され たゴム状弾性材製のバネ部材２とを有し、前記バネ部材２に筒部３と前記筒部３ から放射状に内周方向に延びる所要数（図では２本）の連結部４を設け、前記連 結部４の内周端を前記内筒１に接着してなり、更に、次の構成を備えている。 Next, an embodiment of the present invention will be explained according to the drawings. As shown in FIG. a spring member 2 made of a rubber-like elastic material; A required number (two in the figure) of connecting portions 4 are provided that extend radially inward from the The inner peripheral end of the connecting portion 4 is bonded to the inner cylinder 1, and further includes the following configuration.
【０００７】 すなわち、内筒１に外周方向に向けて２つの突起６が等配で一体突設され、筒 部３に内周方向に向けて４つの突部７が一体突設され、１つの突起６が２つの突 部７に円周方向に挾まれるようにして２組の円周方向のストッパ５が形成されて いる。突起６は内筒１とともに金属板をプレス加工されている。８は筒部３を取 り付けるために該筒部３の外周側に接着された金属製の外筒である。[0007] That is, two protrusions 6 are integrally provided on the inner cylinder 1 toward the outer circumferential direction at equal intervals, and the cylinder Four protrusions 7 are integrally provided on the portion 3 so as to protrude toward the inner circumference, and one protrusion 6 connects two protrusions. Two sets of circumferential stoppers 5 are formed so as to be sandwiched in the circumferential direction by the portion 7. There is. The protrusion 6 and the inner cylinder 1 are formed by pressing a metal plate. 8 removes the cylindrical part 3. This is a metal outer cylinder that is glued to the outer circumferential side of the cylinder part 3 for attachment.
【０００８】 上記構成を備えた防振ゴムは、円周方向のストッパ５を形成したことにより径 方向のバネ定数を低くしたまま連結部４の捩れを一定角度までに抑えて円周方向 の剛性を高めることができる。また円周方向のバネ定数がストッパ５が作動する 前と後で異なることになるために、微小な入力に対しては柔らかく、大きな入力 に対しては固く作動する。[0008] The anti-vibration rubber with the above structure has a diameter of The torsion of the connecting part 4 is suppressed to a certain angle while keeping the spring constant in the circumferential direction low. The rigidity of the material can be increased. Also, the spring constant in the circumferential direction causes the stopper 5 to operate. Because the difference between before and after is soft for small inputs, it is soft for large inputs. It works well against.
