摘要： A circular saw (1) includes a base (2) and a main body (3) mounted on the base and provided with an upper blade guard (7). Disposed behind the upper blade guard (7) is a stopper (22) which includes an upper curved portion (23) and an lower portion (24) coupled to the curved portion (23). One end of the lower portion (24) is attached to the main body (3) with a pivot screw (25) behind the blade guard (7) so as to permit the stopper to pivot on the screw (25) in parallel with a circular blade (5). Additionally, the curved portion (23) includes an arcuate guide slot (26). The stopper (22) further includes a fixing bolt (27) screwed in a boss (29) formed on the rear surface of the blade guard. The bolt (27) includes a lever (30) to be manually operated to selectively secure the curved portion to the bolt and release the curved portion therefrom. When the curved portion (23) is released, its pivotal position relative to the main body towards the base can be manually changed. Provided on the base is a projection (32) which is abutted by the stopper (22) when the main body (3) is lowered toward the base (2). When the curved portion (23) abuts the projection's upper surface (33), the amount of the blade (5) projecting below the base (i.e., the depth of cut) corresponds to the aforementioned relative position of the curved portion (23) with respect to the base (2).

摘要： A circular saw having an improved line-of-sight. The circular saw comprises a motor for rotatably driving a saw blade about an axis to cut a workpiece, a bevel angle being defined between the cutting plane of the saw blade and a surface of the workpiece; a housing supporting the motor; a shoe plate supporting the circular saw on the workpiece to be cut, the shoe plate being pivotably connected to the housing to adjust the bevel angle; a main handle supported by the housing; an auxiliary handle supported by the housing; and an indicator for indicating the bevel angle. Preferably, the main handle, the auxiliary handle and the indicator are arranged so that, in the cutting position, the operator can view the saw blade as the saw blade cuts the workpiece and can view the indicator. The operator holds the main handle with one hand and the auxiliary handle with the other hand. When the operator holds the auxiliary handle with the other hand, the operator's other hand and the auxiliary handle do not obscure the operator's view of the saw blade as the saw blade cuts the workpiece.

摘要： A miter saw including a base portion and a main body portion laterally tiltable and vertically pivotable. The main body portion includes a circular saw blade whose one side is provided with a power transmission mechanism. The mechanism includes a motor shaft pulley fixed to a motor shaft of a motor, a saw blade shaft extending in parallel with the motor shaft and an intermediate shaft extending in parallel with the saw blade shaft and positioned between the motor shaft and the saw blade shaft. On the saw blade shaft, a first saw blade shaft bearing, a flanged abutment portion, a gear and a second saw blade shaft bearing are arrayed in an order from the circular saw blade. On the intermediate shaft, a pinion meshedly engaged with the gear, a first intermediate shaft bearing in alignment with the second saw blade shaft bearing, an intermediate shaft pulley in alignment with the motor shaft pulley and a second intermediate shaft bearing are arrayed in this order from the circular saw blade. The gear and the pinion are positioned closest to the circular saw blade, which permits an axial thickness of the abutment portion to be reduced for reducing entire axial thickness of the power transmission mechanism.

摘要： A portable circular saw providing high visibility to a cutting mark line and sufficient operability even in case of an angled cutting. A slant position fixing member upstands from a front side of a base, and a tiltable plate is provided pivotally to the base. A front end of a saw cover is connected to the tiltable plate by a pivot pin. A main body roratably supporting a circular saw blade is pivotally movable by a pivotal movement of the tiltable plate to change inclination of the circular saw blade relative to the base. The tiltable plate is positioned in confrontation with the slant position fixing member, and fastening unit fixes the tiltable plate to the slant position fixing member to maintain a desired inclination of the circular saw blade. The fastening unit includes a thread extending through an arcuate slot formed in the slant position fixing member and engaging the tiltable plate, and a lever fixed to one end of the thread. The lever has a pressure surface in pressure contact with an abutment surface of the slant position fixing member. The abutment surface is in a form of a slant surface.

摘要： A laser emitter projects a planer light beam to form an optical guideline on a work piece extending in a cutting direction of saw blade. The laser emitter is arranged behind, in the cutting direction, a tangential line of the circumference of the saw blade at an intersection of a bottom surface of the base and the circumference at a front side of the base in the cutting direction. The laser emitter forms the optical guideline behind the intersection in the cutting direction. The laser emitter is supported in respect of the saw blade slidingly in a direction defined by a rotation axis of the saw blade. The saw cover may have a window to transmit the laser beam toward the cutting point. A shutter selectively shutting the window may be provided.

摘要： A circular saw (1) cutting a workpiece at a generally right-angled corner formed between the workpiece and a structure is provided. The saw (1) includes a base plate (2) and a saw blade assembly (3) which has a saw blade (5) rotatably attached thereto and is tiltably mounted on the base plate by first and second pins (12,15) aligned with each other and oriented parallel to the saw blade. This arrangement permits the saw blade (5) to be manually tilted in two directions to desired angles with respect to the base plate (2) within a predetermined range. When the saw blade (5) is disposed at 90 degrees relative to the top surface of the base plate (2), the common longitudinal axis (O2) of the first and second pins (12) and (15) is spaced apart from the center plane (L) of the saw blade (5) toward the motor by a predetermined distance (S) as measured along a path orthogonally intersecting the center plane and the axis.
