Abstract: A metal wire may be provided inside a hanger portion extending with an annular shape and which is integrally formed with an outer casing. An electric power tool may be prevented from falling, etc. due to deformation or breakage of the hanger portion by being reinforced by the wire.

Abstract: A power tool includes a body housing including a first grip, inlet facing a front surface of the first grip, first outlet, and second outlet; a brushless motor held on the body housing and including a rotational shaft; an output unit supported on the body housing in a reciprocable manner; a power transmission mechanism between the brushless motor and the output unit in the body housing to transmit rotational motion of the rotational shaft to the output unit; a controller held on the body housing to control the brushless motor; and a fan held on the body housing and mounted on the rotational shaft. The body housing allows air drawn through the inlet and having cooled the brushless motor to be divided into first and second outlet blows respectively cooling the power transmission mechanism and discharged through the first outlet, and cooling the controller and discharged through the second outlet.

Abstract: A reciprocating tool easily supplies a lubricant, such as grease (lubricating oil), to a mechanism for reciprocating a slider, and prevents a lack of lubricant. A reciprocating saw as a reciprocating tool includes a motor, a reciprocating conversion mechanism that converts rotation of the motor to reciprocation, a slider connected to the reciprocating conversion mechanism and being reciprocable, and a slider guide that supports the slider in a reciprocable manner and includes a lubricant-passage member in contact with the slider to allow passage of at least part of a lubricant through the lubricant-passage member, and a lubricant reservoir located adjacent to the lubricant-passage member to store the lubricant.

Abstract: A reciprocating saw serving as reciprocating tool is equipped with a motor, a drive transmission mechanism that converts rotation of the motor into reciprocating motion, a rod that is connected to the drive transmission mechanism and that engages in reciprocating motion, and an upper roller and a lower roller that are capable of rolling and that have depressed portions that are capable of coming in contact with the rod, wherein the cross-section of the rod has no corners, and the depressed portions of the upper roller and the lower roller have hourglass-like profiles.

Abstract: A ventilation apparatus is mountable on a garment, such as a jacket. The ventilation apparatus includes a fan that is rotationally driven by a motor and is housed in a main body that includes intake ports and exhaust ports. The motor may be a brushless motor. In addition or in the alternative, a main body of the motor may be shorter than blades of a fan mounted on a drive shaft of the motor.

Abstract: A rechargeable radio is provided with battery attachment portion for attaching electric power tool battery and radio communication section. An input section, of which an operation input is performed in rechargeable radio, is connected to control section. Input section includes an operation part and microphone part. Output section, of which a sound output and a display output are performed in rechargeable radio, is connected to control section. Audio output section outputs sound based on sound output signal transmitted from control section. Rechargeable radio is configured to access to radio communication function of smart phone via radio communication section, whereby it is possible to perform sound input and output relating to smart phone through rechargeable radio. As a result, added values of rechargeable radio are improved, thereby achieving improvement in terms of interests of rechargeable radio including convenience.

Abstract: A reciprocating electric power tool in one aspect of the present invention includes an attachment unit, a motor, a power transmission unit, and a controller. The controller is configured to operate the motor at a first speed when activated; to operate the motor at a second speed that is higher than the first speed when a first condition is satisfied after activation; and, to operate the motor at a third speed that is higher than the second speed when a second condition is satisfied after the first condition is satisfied.

Abstract: A cutting tool may include an outer housing that receives a motion conversion unit and a drive device therein. A cutting blade may be driven by the drive device via the motion conversion unit. A dust preventing device may prevent dust from reaching to the drive motor from between the outer housing and the motion conversion unit.
