Abstract:
1. A method for producing a columnar member container for holding a columnar member in a cylindrical housing, comprising: wrapping a shock absorbent member around said columnar member; supporting one end portion of one of said cylindrical housing and said columnar member, on a support member; arranging the other one of said cylindrical housing and said columnar member in a cylindrical guide member formed with a tapered portion inside thereof and placed on the same axis as a longitudinal axis of said support member; inserting said shock absorbent member and said columnar member into said cylindrical housing through said tapered portion of said guide member; pressing a pushing member to the other one of said cylindrical housing and said columnar member so as to be moved along a longitudinal axis thereof relative to each other, to accommodate said shock absorbent member and said columnar member in said cylindrical housing; moving said support member and a shrinking mechanism for reducing a diameter of a part of said cylindrical housing, relative to each other, with the one end portion of one of said cylindrical housing and said columnar member being supported on said support member, to move said cylindrical housing, shock absorbent member and columnar member in a body, to be placed at a certain position relative to said shrinking mechanism; and actuating said shrinking mechanism to reduce the diameter of the part of said cylindrical housing.
