PURPOSE: An improved holder is provided having high performance by optimizing an intrinsic influence quantity with respect to the surer holding of optical components. CONSTITUTION: An angle of inclination of a chamfered surface (6) is set in a range of 40 to 500 and a boundary wall (11) of an insert groove (4) existing within the range of the optical components (2 and 3) is placed at a height of a chamfered edge facing a socket (1). The boundary wall (11) of the insert groove (4) existing in front of the optical components (2 and 3) is undercut at an angle of 10 to 15 deg., by which the depth of the insert groove (4) is made larger by 0.15 to 0.2 mm than the radius of an annular element (5). The free opening between the chamfered edge (10) existing on the optical components (2 and 3) and the front edge (12) of the undercut boundary wall (11) of the insert groove (4) is made equal to 0.8 times the diameter of the annular element (5). |
