Abstract: The node is located on a first position side of the vibration exciter or a second position side of the vibration receiver with respect to the one end of the first beam and the one end of the second beam in an axial direction of an axis passing through the first position and the second position. A rotational displacement of the node is excited by a translational displacement of the vibration exciter and a translational displacement of the node associated with the translational displacement of the vibration exciter, and exhibits anti-resonance at a frequency within a frequency range higher than a first resonance frequency of the vibration isolating structure and lower than a second resonance frequency.

Abstract: A connector connecting a first member and a second member, includes at least one spiral part in a shape where the thickness is added to a spiral surface formed by a spiral trajectory in which a line, connecting a first point located on a center axis passing through a first position on the first member side and a second position on the second member side and a second point located at a position away from the center axis, rotates around the center axis with the first point as a center while the first point moves in a direction along the center axis. The connector is integrally molded as a whole. This makes it possible to reduce the number of parts and simplify the assembly process compared to the ball joint and universal joint.
