<p>PURPOSE:To provide a mold for casting a propulsive coil and a spacer, in which a coil body can be fixed to a mold for casting without adjusting the size of the spacer even when the size of the coil body is dispersed within the tolerance of the size of the coil body and which have excellent mass productivity and high voltage resistance. CONSTITUTION:Spacer inserting sections 13 and recessed sections 5a, 5b having a shape corresponding to a propulsive coil are formed to molds 11, 12 respectively. An adjusting shaft 15 engaged with the mold 12 (or 11) by a screw and a moving body 16 freely slid in the recessed section 14b by the adjusting shaft 15 are mounted to the spacer inserting section 13. A tapered spacer inserting groove 19 is formed to an opening section on the recessed section 5a (or 5b) of the recessed section 14b, and the base of the spacer inserting groove 19 is formed by the end face of the moving body 16.</p> |
