PURPOSE:To press-contact a composition plane making unnecessary a spring, a screw, and a precision jig, by providing an elastic frame made of a resin, etc., and putting constrainedly the mutual position of plural cores regulating so that they are coupled at a prescribed joining plane. CONSTITUTION:An elastic frame 5 is formed with a material, such as the resin, etc., at each channel as an independent another parts, and it is constituted of a finger part 7 and a main body part 9, and a groove 8 is formed recessedly at its outer wall. Also, at the elastic frame 5, the first containing part 11 which is enclosed by the finger part 7, and forms the guide of the first core 1, and the second containing part 12 which is enclosed mainly by the finger part 7, and forms the guide of the second core 2, are provided. And since the containing parts 11 and 12 are set smaller than the cores 1 and 2, the containing parts 11 and 12 of the elastic frame 5 receive the cores 1 and 2 by deforming themselves. Consequently the whose planes of cores 1 and 2 are pushed back elastically by the inner wall of the containing parts 11 and 12. In this way, the press- contact of the joining plane can be obtained, and the coupling in one body of the whole of the heads can be stabilized making unnecessary the screw and the precision jig, etc.
