Abstract
A test tube holder includes a test tube insertion adapter having an adapter body and an elastic ring. The adapter body includes a flange section which contacts an opening of the cylindrical hollow, an annular section which ranges with the flange section and is fitted on the inner surface of the opening, a plurality of flat spring sections whose proximal end portions are arranged at regular intervals along the circumference of the annular section and connected to the annular section and whose distal end portions extend inward in the cylindrical hollow and bent toward the axis of the adapter body, and contact sections which are formed on the inner surfaces of distal end portions of the flat spring sections. The elastic ring is provided to bind the flat spring sections together while surrounding the outer surfaces of the flat spring sections.
