<p>PROBLEM TO BE SOLVED: To shorten the manufacturing time of a brake stator and to prevent a coil from being cut. SOLUTION: A coil 10 is fitted in the groove 6 of a stator body 2 so as to have play and a friction material 14 is fitted in the opening side of the groove 6. This friction material 14 has a rotation stopping groove in a side facing the coil 10 and a sealing agent feeding port 15 composed of a tapered hole in its thickness direction. SPS as a thermoplastic resin is injected through the sealing agent feeding port into the groove 6. Thus, the coil 10 is insulated by SPS and fixed in the groove 6 and the friction material 14 is fixed to the stator body 2 in rotational and axial directions by engagement between hardened SPS and the rotation stopping groove and between the SPS and the sealing agent feeding port 15.</p> |
