し電子管１９への固定が可能となる。First, as shown in FIG. 2, the electric component has four static magnets 11 and 12 in a cylindrical holder 10 made of synthetic resin having a ring-shaped support 9 in the middle portion (cylindrical portion).
It is configured by incorporating two purity magnets 13 and a spacer 14. The cylindrical holder 10 is provided with a plurality of arc-shaped pieces 15 whose outer circumferential surface gradually increases in diameter from one end to the other end and whose circumferential surface is a circular arc so as to form a circle to form the fixing portion 18. . Among the arcuate pieces 15 forming the fixing portion 18, several arcuate pieces 15 located within about a semicircle have an outer peripheral surface extending from one end to the other end of the semicircle as shown in FIGS. Is configured to gradually increase in diameter,
Several arc-shaped pieces 15 located in the other semicircles are also configured similarly. A tightening ring 17 provided on the inner peripheral surface is provided at a position corresponding to the arc-shaped piece 15 in which two projecting portions 16 each having a gradually smaller diameter are continuously provided from one end to the other end of the semicircle of the inner peripheral surface. By fitting and rotating the tightening ring 17 as shown in FIGS. 4A and 4B, the arcuate piece 15 is narrowed inward, and a force is applied to the electron tube 19 in the radial direction to act on the electron tube 19. Can be fixed.
