Abstract
PURPOSE:To firmly hold alignment magnets in the optimum condition throughout a long period of time, by fixing the alignment magnets to the stepped part of a coil bobbin through an O-ring. CONSTITUTION:Alignment magnets 4, 5, in the rear side of which an O-ring 13 is arranged, are fixed by tightening a clamp ring 14 with a previously provided screw part to a threaded part provided in the final end part of a coil bobbin 3, squeezing the O-ring 13 and strongly pressing the alignment magnets 4, 5 to a stepped part of the coil bobbin 3. In this way, because the alignment magnets 4, 5 previously adjusted to a position in the optimum condition are firmly held to the coil bobbin 3 and the O-ring 13 made of rubber acts as a shock absorbing material, a shock, vibration and the like from the outside can be absorbed to hold the magnets in the optimum condition throughout a long period of time.
