Vibration insulating member

A vibration insulating member configured to be equipped between one component and an other component, the vibration insulating member comprising:

• a through hole forming portion formed of an elastic material, the through hole forming portion having a through hole in which a connection member is configured to be inserted to connect the one component with the other component;
• at least one contact portion projected radially inward from an inner wall of the through hole forming portion, the at least one contact portion having an inner wall on its radially inside;
• and
• a collar formed of a material, which is higher in compressive strength than the elastic material of the at least one contact portion, wherein
• the collar includes a body and a seat portion,
• the body is in a tubular shape and configured to be located between an outer wall of the connection member and the inner wall of the through hole forming portion,
• the connection member is configured to be inserted in the body,
• the seat portion is equipped to one end of the body,
• the seat portion is configured to be in contact with the connection member and an end surface of the at least one contact portion, the end surface of the at least one contact portion being nonparallel to a center axis of the through hole,
• the seat portion is configured to receive a connection force, which the connection member exerts to connect the one component with the other component,
• when the connection member is inserted in the through hole, the outer wall of the connection member forms at least one gap with the inner wall of the through hole forming portion and is in contact with the inner wall of the at least one contact portion via the body, and
• a length of the body of the collar is shorter than a length of the through hole of the through hole forming portion in an axial direction.
