Abstract

A vibration insulating member is equipped between one component and an other component. The vibration insulating member includes a through hole forming portion and a contact portion. The through hole forming portion is formed of an elastic material to have a through hole in which a connection member is inserted to connect the one component with the other component. The contact portion is projected radially inward from an inner wall of the through hole forming portion. The contact portion has an inner wall on a radially inside. When the connection member is inserted in the through hole, an outer wall of the connection member forms a gap with the inner wall of the through hole forming portion and is in contact with the inner wall of the contact portion.

First claim

What is claimed is:

1. 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.

2. The vibration insulating member according to claim 1 , wherein
the through hole forming portion has an outer wall on a radially outside, and
the outer wall of the through hole forming portion defines a stationary groove to which an outer wall of the one component is configured to be fixed.

3. The vibration insulating member according to claim 1 , wherein
the through hole forming portion has one end surface and an other end surface, which are nonparallel with a center axis of the through hole, and
the at least one contact portion extends from the one end surface to the other end surface.

4. The vibration insulating member according to claim 1 , wherein
the at least one gap has a sectional shape perpendicular to a center axis of the through hole, and
the sectional shape is line-symmetrical about an imaginary line, which passes through a point on the center axis.

5. The vibration insulating member according to claim 1 , wherein the at least one contact portion includes a plurality of contact portions.

6. The vibration insulating member according to claim 5 , wherein
the at least one gap includes a plurality of gaps, and
the plurality of gaps are located on a concentric circle, which is centered at a point on a center axis of the through hole.

7. The vibration insulating member according to claim 6 , wherein the plurality of gaps are located at constant angular intervals relative to the point on the center axis of the through hole.

8. The vibration insulating member according to claim 1 , wherein the through hole forming portion and the at least one contact portion are integrally formed with each other.

9. The vibration insulating member according to claim 1 , wherein
the seat portion is formed in an annular shape,
the seat portion is located at the one end of the body on an opposite side of the other component,
the through hole forming portion has one end surface located on an opposite side of the other component,
the seat portion has one end surface on a side of the through hole forming portion, and
the one end surface of the seat portion is in contact with the one end surface of the through hole forming portion.

10. The vibration insulating member according to claim 9 , wherein
the seat portion has an other end surface on an opposite side of the through hole forming portion, and
the other end surface of the seat portion is configured to be in contact with a head of the connection member.

11. The vibration insulating member according to claim 10 , wherein
the connection member is a bolt having the head.

12. The vibration insulating member according to claim 11 , wherein
the head has a head width in a direction perpendicular to the axial direction,
the body of the collar has a body diameter in the direction perpendicular to the axial direction, and
the head width is greater than the body diameter.

13. The vibration insulating member according to claim 1 , wherein
when the connection member is inserted in the through hole, an outer wall of the body forms the 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.

14. The vibration insulating member according to claim 13 , wherein
when the connection member is inserted in the through hole, the outer wall of the connection member makes contact with an inner wall of the body.

15. The vibration insulating member according to claim 1 , wherein
the connection member is configured to be screwed directly to the other component.

16. The vibration insulating member according to claim 1 , wherein
the through hole forming portion is configured to be directly in contact with the other component.
