ABSTRACT:
The invention is directed to a power plug which has a high physical strength against traction forces tending to pull the blades out of the plug body. The power plug of the invention realizes the above characteristics by comprising a pair of blades, each of the blades having one end connected to a cord, and a blade retaining member. The blade retaining member is made of an electrically insulating material, and has retaining portions which retain the blades so that they are not displaced relative to the blade retaining member. A resin molded plug body embeds the blade retaining member, proximal end portions of the pair of blades at which the blades are connected to the cord, and an end portion of the cord to which the blades are connected.
