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 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.
