A device for mounting a blade on a reciprocally movable blade carrier of a cutting tool includes a blade pressing member and a blade pressing surface formed on the blade carrier, so that the blade can be pressed against the blade pressing surface by the blade pressing member. A retainer member serves as a guide for the pressing member, so that the pressing member can move in a direction substantially perpendicular to the pressing surface between a first position for pressing the blade against the pressing surface and a second position for releasing the pressing force of the pressing member. An operation member is shiftable relative to the blade carrier and is operable by an operator for moving the pressing member between the first position and the second position. A ball is interposed between the pressing member and the operation member. A contacting surface is formed on the operation member, so that the ball can roll along the contacting surface.

Blade mounting devices for reciprocating cutting tools

A miter saw includes a support mechanism for supporting a miter saw unit relative to a base in such a manner that the miter saw unit is both vertically and laterally pivotable. A position determining mechanism serves to selectively determine the position of the saw unit at any of positions including a vertical position where a saw blade is positioned substantially vertically relative to the base, and leftward and rightward pivoted positions where the saw blade is inclined laterally leftwardly and laterally rightwardly from the vertical position by a predetermined angle, respectively. The position determining mechanism includes movable side stopper members and fixed side stopper members on which the movable side stopper members abut, respectively. The movable side stopper members are mounted on a movable member which pivots laterally with the miter saw unit. The fixed side stopper members are mounted on a fixed member which is non-laterally pivotally movably mounted on the base. The movable side stopper members abut on their corresponding fixed side stopper members when the miter saw unit is at the vertical position and at the leftward and rightward pivoted positions, respectively.

Miter saw

A miter saw includes a base for placing a work thereon, a miter saw unit having a saw blade mounted thereon, and a slide support mechanism comprising a slide mechanism having a slide shaft mounted on one of the miter saw unit and the base, and a sleeve member mounted on the other of the miter saw unit and the base. The sleeve member is slidably movable relative to the spline shaft in an axial direction of the slide shaft, and the rotational position of the sleeve member is fixed relative to the slide shaft around an axis of the spline shaft. First and second covers are disposed around the slide shaft on opposite sides of the sleeve member forming first and second air chambers in communication with each other.

A miter saw includes a base on which a work is placed. A miter saw unit supports a saw blade and has a motor for rotatably driving the saw blade. A support mechanism is provided supporting the miter saw unit relative to the base in such a manner that the miter saw unit is laterally leftwardly and rightwardly pivotable from a vertical position. A biasing member is interposed between the miter saw unit and the base for biasing the miter saw unit in a direction opposite to at least one of the directions of the lateral pivotal movement of the miter saw unit when the miter saw unit is laterally pivoted.

A miter saw includes a base for placing a work thereon and a miter saw unit supported by a support mechanism relative to the base. The miter saw unit supports a saw blade and a motor for driving the saw blade. The motor has a motor shaft extending in a longitudinal direction of the motor. A transmission mechanism serves to transmit rotation of the motor to the saw blade. The support mechanism supports the miter saw unit in such a manner that the miter saw unit is vertically pivotable and that the miter saw unit is laterally pivotable from a vertical position to an inclined position. The rotational axis of the saw blade extends substantially horizontally when the miter saw unit is at the vertical position, and the rotational axis of the saw blade extends obliquely relative to the horizontal direction when the miter saw unit is at the inclined position. The motor is positioned on one lateral side of the miter saw unit toward the inclined position. The motor shaft of the motor extends obliquely relative to the rotational axis of the saw blade in such a manner that the motor shaft extends obliquely upwardly relative to the saw blade when the miter saw unit is at the vertical position.

A miter saw including a base for placing a workpiece thereon, a substantially circular turn table mounted on the base, a slide member radially slidably supported in the turn table, an arm mounted to the slide member, and a miter saw unit provided above the turn table and vertically swingably mounted to the arm in such a manner as to be opposed to the turn table. The miter saw unit has a cutting tool such as a circular saw blade and means for driving the cutting tool. A supporting portion of the slide member with respect to the turn table is located at a position in the vicinity of a load application point of the cutting tool.
