Document Type and Number:
WIPO Patent Application WO/2005/088810
Kind Code:
A1
Abstract:
A brushless motor enabling an increase in workability for electrical connection between an exciting coil and a circuit board disposed in a casing and the securement of assured waterproofness at a connected portion. A waterproof case (25) in which a terminal bar (24) is buried comprises a large diameter part (25a) formed in a hollow bottomed cylindrical shape and a small diameter part (25b) having an O-ring (27) wound on the outer peripheral surface thereof. The U-shaped end part of the terminal bar (24) connected to the end part of the exciting coil (7) is positioned at the hollow portion of the large diameter part (25a). On the other hand, a part of the roughly linear portion of the terminal bar (24) extending from the U-shaped one end part is axially buried in the small diameter part (25b). The remaining portion of the terminal bar (24) is projected from the small diameter part (25b), the end part thereof is soldered to the circuit board (4), and the small diameter part (25a) of the waterproof case (25) is fitted into a cylindrical fitting part (26) formed in the casing (1) to secure watertightness.
