Abstract: A reciprocating tool includes a toggle switch that is turned on or off by tilting a lever, and a switch lever in a motor housing. The switch lever includes an engagement frame into which the lever is inserted, and can slide in a tilting direction. The switch lever is slid to tilt the lever to an ON position or an OFF position through a sliding operation of the switch lever from the outside. An engagement portion of the switch lever on a side closer to the ON position of the lever is provided with a slanted guide surface that guides the lever in the ON position to the OFF position when the toggle switch is attached into an upper housing having the switch lever attached thereto.

Abstract: A dust collecting attachment that is mounted on a sander includes a suction portion mounted on a portion of a front housing where an output shaft projects, a flexible hose having a front end of the flexible hose connected to the suction portion, a discharge portion connected to a rear end of the flexible hose and a changeable member placed on both a motor housing and the discharge portion. The changeable member allows the discharge portion to be mounted at any position around an axis of the motor housing.

Abstract: The ink for ink jet recording includes a sparingly water-soluble alkanediol, a resin, and a coloring material, wherein the content of the coloring material is from 1 to 3% by mass based on the total mass of the ink, the surface tension is from 21 to 25 mN/m, and the thixotropic index (TI) represented by the following formula (1), as determined at a time point when its content becomes 40% by mass based on the total mass before the evaporation of the ink by the evaporation of the ink, is from 2 to 110: TI=?(1 s?1)/?(1000 s?1)??(1).
