Abstract
Official abstract text for this publication.
A method joins members for joining a first member being cylindrical and a second member being plate-shaped and having an opening. This method includes: inserting a first member into an opening of the second member; inserting an elastic body into the first member; guiding an outer diameter side of the first member with a pair of outer dies on both sides of the second member; and compressing an elastic body in the first member with a pair of inner dies. The inner dies compress the elastic body within a range in which the outer dies are positioned.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for joining members for joining a first member being cylindrical and a second member being plate-shaped and having an opening, the method comprising: inserting the first member into the opening of the second member; inserting an elastic body into the first member; guiding an outer diameter side of the first member with a pair of outer dies on both sides of the second member such that the first member is positioned within an opening of each of the outer dies; and compressing an elastic body in the first member with a pair of inner dies, wherein the inner dies compress the elastic body within a range in which the outer dies are positioned. 2. The method for joining members according to claim 1 , wherein the inner dies are arranged one above the other and the elastic body is compressed by at least any one of the inner dies. 3. The method for joining members according to claim 1 , wherein the outer die includes a plurality of split dies. 4. The method for joining members according to claim 1 , wherein the outer die is formed with a recessed portion in which an opening area gradually increases toward an end surface, and the inner die does not protrude into the recessed portion. 5. The method for joining members according to claim 1 , wherein the outer die includes a plurality of split dies, and wherein the outer die is formed with a recessed portion in which an opening area gradually increases toward an end surface, and the inner die does not protrude into the recessed portion. 6. The method for joining members according to claim 2 , wherein the outer die is formed with a recessed portion in which an opening area gradually increases toward an end surface, and the inner die does not protrude into the recessed portion. 7. The method for joining members according to claim 2 , wherein the outer die includes a plurality of split dies, and wherein the outer die is formed with a recessed portion in which an opening area gradually increases toward an end surface, and the inner die does not protrude into the recessed portion.
