A brushless motor has a first coupler that includes a molded body with an annular member and a plug integrally combined with a peripheral side wall of the annular member. The plug houses terminal rods therein. Bridges project radially inward from an inner peripheral wall surface of the annular member. Connectors joined to respective leads that extend from an electromagnetic coil are mounted on radial inner ends of the bridges. The bridges axe provided in pairs of adjacent bridges. In each of such pairs, the bridges project in parallel with each other from an inner peripheral wall surface of the annular member.
