Mount bush

A mount bush comprising:

• a tube member;
• a shaft member disposed inside the tube member coaxially with an axis of the tube member and having a coil;
• a first liquid chamber disposed at an upper side in an internal space between the tube member and the shaft member in a gravity upward/downward direction;
• a second liquid chamber in communication with a lower side of the first liquid chamber in the gravity upward/downward direction and containing a magnetic viscoelastic fluid;
• and
• a third liquid chamber in communication with a lower side of the second liquid chamber in the gravity upward/downward direction and having a porous body,
• wherein the coil is disposed such that a magnetic path that passes through the second liquid chamber in an orientation along at least one of an axial direction along the axis and a radial direction perpendicular to the axial direction is formed through electrical conduction,
• wherein the second liquid chamber includes:
• an axial passage that communicates with the first liquid chamber and that extends in the axial direction;
• and
• a shaft-perpendicular passage that communicates with the axial passage and the third liquid chamber and that extends in the radial direction, and
• wherein the coil is disposed such that a magnetic path, which passes through the axial passage in an orientation along the radial direction and passes through the shaft-perpendicular passage in an orientation along the axial direction, is formed through the electrical conduction.
