PURPOSE:To form as one body an exact and long fitting length and a stopper by inserting and installing a cylindrical member having an optical fiber connector inserting hole to an inserting opening side of an optical fiber connector, and also forming a stepped part as one body with a body. CONSTITUTION:A recessed hole 12 having a step 11 is formed in the center of the inside of a body 10, and a hole 13 being an optical path is pierced in the step 11 part. A cylindrical member 15 is inserted and installed to the recessed hole 12, but this cylindrical member 15 consists of a simple shape, and as for an inside diameter hole 16 and an outside surface 17, a precise finish state and a degree of concentricity are guaranteed and secured. A length of the inside diameter 16 is several times as long as the hole diameter 16. The recessed hole 12 to which the cylindrical part 15 is inserted and installed has an inside diameter corresponding to an outside diameter of the outside surface 17, therefore, it obtains its corresponding length, also is set to a length exceeding that which corresponds to the inside diameter size, and also the stepped part 11 is formed easily. In this way, an exact and long fitting length and a stopper can be formed as one body. |
