Abstract: An impact tool is less likely to have a shorter service life. An impact tool includes a motor, a spindle, a hammer, an anvil, and a lid. The spindle is rotatable by the motor. The spindle has an opening in a rear end face of the spindle, an internal space extending frontward from the opening and including a first space containing a lubricant oil and a second space connecting to a rear end of the first space, and a first feed port in an outer circumferential surface of the spindle. The hammer surrounds the spindle. The anvil is strikable by the hammer in a rotation direction. The lid is placeable through the opening into the second space. The first feed port allows supply of the lubricant oil from the first space to between the spindle and the hammer.

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.
