Abstract
A power tool includes a brushless motor having a stator and a rotor, which includes a rotary shaft extending in a front-rear direction of the power tool. The rotary shaft rotates a spindle that extends in an up-down direction of the power tool. A fan is fixedly coupled to the rotary shaft and rotates therewith. A switch is disposed rearward of the brushless motor and a controller is disposed rearward of the switch in the front-rear direction. A battery pack is disposed rearward of the controller. A main-body housing houses the brushless motor, the switch and the controller. The main-body housing includes a first tubular part, which houses the brushless motor, and a second tubular part, which houses the switch. The diameter of the second tubular part is smaller than the diameter of the first tubular part.

21. A power tool comprising:
-
a tubular housing having a front-rear direction defined along a longitudinal direction of the tubular housing, a motor housed in the tubular housing, a switch disposed in the tubular housing and oriented such that a button of the switch faces forward in the front-rear direction, the button being movable in the front-rear direction, an operating member disposed on an exterior surface of the tubular housing and being slidable in the front-rear direction, a slide part slidably housed within the tubular housing, the slide part being operably coupled to the operating member so as to be slidable in the front-rear direction in conjunction with the operating member, and a pressing mechanism operably disposed between the slide part and the switch, the pressing mechanism being configured to turn ON the switch when the slide part is moved forward in the front-rear direction by the operating member and to turn OFF the switch when the slide part is moved rearward in the front-rear direction by the operating member. - View Dependent Claims (22, 23, 24, 25, 39)

33. A power tool comprising:
-
a tubular housing having a front-rear direction defined along a longitudinal direction of the tubular housing, the tubular housing comprising a first tubular housing portion disposed frontward of a second tubular housing portion that is narrower than the first tubular housing portion, a motor disposed in the first tubular housing portion, a push button switch disposed in the second tubular housing portion and oriented such that a button of the push button switch faces forward in the front-rear direction, the button being movable in the front-rear direction, a switch knob disposed on an exterior surface of the first tubular housing portion and being slidable in the front-rear direction, a slider slidably housed within the first tubular housing portion, the slider having a first end portion coupled to the switch knob, and a lever pivotably supported within the tubular housing, wherein a first end portion of the lever is coupled to a second end portion of the slider, and a second end portion of the lever is configured to depress the button of the push button switch rearward when the slider is moved forward in the front-rear direction by the switch knob and to allow the button to move frontward when the slider is moved rearward in the front-rear direction by the switch knob. - View Dependent Claims (34, 35, 36, 37, 38)
