Patent number: 9368765Abstract: Rubber cover main bodies close opening shapes of terminal-connection openings when a battery pack is placed alone without being mounted on a tool body. When the battery pack is removed from the tool body and is placed alone, it is possible to regulate the entry of foreign materials, such as water or dust, by the rubber cover main bodies. Further, when body-side connection terminals are connected to battery-side connection terminals, the rubber cover main bodies themselves can be deformed due to elasticity according to the slide movement of the body-side connection terminals such that the body-side connection terminals can be inserted into the rubber cover main bodies. Accordingly, it is possible to protect the battery-side connection terminals in the terminal-connection openings such that the battery-side connection terminals are not damaged by regulating the entry of foreign materials from the terminal-connection openings without hindering electrical connection caused by slide mounting.Type: GrantFiled: October 17, 2011Date of Patent: June 14, 2016Assignee: MAKITA CORPORATIONInventor: Hideyuki Taga

Publication number: 20160020676Abstract: In an electric power tool which houses a motor and a controller for controlling drive of the motor, the controller has a circuit board on which electric components are mounted and a heat radiation member which radiates heat of the electric components. The heat radiation member has a facing part which faces the circuit board in parallel to a board surface of the circuit board. The facing part is provided with steps by which a distance between the facing part and the board surface of the circuit board varies. Furthermore, the facing part of the heat radiation member is provided with a first facing part in which a relative distance with respect to the board surface of the circuit board is reduced.Type: ApplicationFiled: July 6, 2015Publication date: January 21, 2016Inventors: Motohiro OMURA, Ryosuke SUZUKI, Hideyuki TAGA
