Abstract

A shock absorber which can be easily attached and which can reduce the installation space is provided. The shock absorber in accordance with the present invention is characterized by including a front wall to receive shock, a rear wall opposing the front wall, and peripheral walls connecting peripheries of the front wall and the rear wall, and at least one attaching section to attach onto an attaching object is formed to be integral with the rear wall, and shock received by the front wall is propagated via the rear wall to the attaching object.

First claim

The invention claimed is:

1. A shock absorber, comprising:
a front wall to receive shock;
a rear wall opposing the front wall; and
peripheral walls connecting peripheries of the front wall and the rear wall to each other, wherein
at least two attaching sections configured to attach onto an attaching object is formed to be integral with the rear wall, the at least two attaching sections comprising at least a hollow first attaching section and a solid second attaching section, a body of the shock absorber is formed in a hollow shape and a hollow section of the body is integral with a hollow section of the first attaching section, and
shock received by the front wall is propagated via the rear wall to the attaching object,
wherein a parting line extends along one edge and other one edge of the rear wall, the at least two attaching sections being formed on the parting line, and
the parting line extends with inflection from one edge to other one edge in a longitudinal direction of the rear wall, and
positions of the at least two attaching sections formed on the parting line are different from each other in a transverse direction of the rear wall.

2. The shock absorber in accordance with claim 1 , wherein the first attaching section projects farther from the rear wall than the second attaching section.

3. The shock absorber in accordance with claim 2 , wherein the second attaching section comprises at least two planar sections, and the at least two planar sections being coupled with each other by a coupling section formed in a thinner section that is thinner than the planar sections.

4. The shock absorber in accordance with claim 1 , wherein the second attaching section comprises at least two planar sections, and the at least two planar sections being coupled with each other by a coupling section formed in a thinner section that is thinner than the planar sections.

5. A shock absorber, comprising:
a front wall configured to receive shock;
a rear wall opposing the front wall;
and peripheral walls connecting peripheries of the front wall and the rear wall to each other, wherein at least two attaching sections configured to attach onto an attaching object is formed to be integral with the rear wall, the at least two attaching sections comprising at least a hollow first attaching section that comprises a hollow concaved-shaped notch section depressed toward an inside of the first attaching section, a body of the shock absorber is formed in a hollow shape and a hollow section of the body is integral with a hollow section of the first attaching section, and shock received by the front wall is propagated via the rear wall to the attaching object,
wherein a parting line extends along one edge and other one edge of the rear wall, the at least two attaching sections being formed on the parting line, and
the parting line extends with inflection from one edge to other one edge in a longitudinal direction of the rear wall, and positions of the at least two attaching sections formed on the parting line are different from each other in a transverse direction of the rear wall.

6. The shock absorber in accordance with claim 5 , wherein the notch section opens toward a direction that the attaching section other than the first attaching section is not formed.

7. The shock absorber in accordance with claim 5 , wherein the at least two attaching sections comprises a solid second attaching section.

8. The shock absorber in accordance with claim 7 , wherein the first attaching section projects farther from the rear wall that the second attaching section.

9. The shock absorber in accordance with claim 7 , wherein the second attaching section comprises at least two planar sections, and the at least two planar sections being coupled with each other by a coupling section formed in a thinner section that is thinner than the planar sections.
