an inverted bowl-shaped casing made of an elastic material such as soft rubber that is integrally molded on the base plate and forms an air chamber of a predetermined volume between the casing and the base plate; A columnar protrusion extending from the upper wall toward the base plate and having a lower end in contact with the base plate is formed into a convex spherical surface with a predetermined curvature, and a portion of the base plate facing the columnar protrusion is provided with a columnar protrusion. A vibration absorbing device characterized in that a concave spherical surface is provided with a curvature larger than the curvature of the convex spherical surface. (2) In claim (1) of the utility model registration, the vibration is characterized in that the columnar protrusion has a length such that the convex spherical surface at the lower end contacts the concave spherical surface of the base plate even when no load is applied. Absorption device. (3) The vibration absorbing device according to claim (1) or (2), characterized in that a suitable lubricant is applied to a contact surface between the convex spherical surface and the concave spherical surface. (4) Scope of claims for utility model registration (1), (2) or (3)
In the vibration absorbing device, the base plate is made of an elastic material such as soft rubber, like the casing.
