PURPOSE:To attempt improvement in liquid tightness as well as prevent deviation in position of a magnet coil owing to vibration and the like by fixing the electromagnetic coil to a coil case using an adhesive of synthetic region superior in water resistance. CONSTITUTION:An electromagnetic coil 1 held in the form of a cylinder by bundling etc. is contained in a coil case 2 composed of double cylinders with a base formed so as to have a cross section like a character of U. The electromagnetic coil 1 is securely fixed to the inside of the case 2 using a strong adhesive layer 3 provided with liquid tightness. An adhesive for an urethane construction and a reactor-type silicone adhesive are suitable as the adhesive. |
