Abstract: A guiding device for a saw band or a sawblade of a sawing machine is provided, which has at least one holder with at least one gliding part and/or at least one roll for an at least temporary gliding and/or rolling contact with the saw band or sawblade. The at least one gliding part and/or the at least one roll is provided on the holder in a movable fashion in reference to the holder, with the at least one gliding part and/or the at least one roll being movable in reference to the holder via at least one piezo-actuator, essentially perpendicular to the direction of movement of the saw band or sawblade. A sawing machine with such a guiding device is also provided.

Abstract: To provide a cutting machine that suppresses swinging of the cutting portion when the battery pack is attached or detached, the cutting machine includes a cutting portion, a base, and a swing support mechanism. The cutting portion includes: a motor, a motor housing accommodating the motor, an output shaft configured to be rotated upon rotation of the motor, a battery pack serving as a power source of the motor, and a battery pack attaching portion including a pair of rail portions with which the battery pack is engageable, where a cutting blade is configured to be detachably attached to the output shaft. The base has a contact surface on which a workpiece is configured to be placed. The swing support mechanism is connected to the base and the cutting portion and includes a swing shaft extending in parallel to the output shaft. The swing support mechanism supporting the cutting portion such that the cutting portion is swingable about the swing shaft between a top dead center and a bottom dead center in a direction parallel to a side surface of the cutting blade. The pair of rail portions extend in a direction crossing the side surface of the cutting blade.

Abstract: It is an object of the invention to provide a technique for increasing the degree of freedom in designing a grip part in order to improve operability of a power tool. A representative electric vibration tool 100 is provided which mainly includes a body housing 101, an inner housing 110, a driving motor 115 and a spindle 124. A blade 145 as a tool accessory is held between the spindle 124 and a clamp shaft 127 and driven by the driving motor 115. The driving motor 115 and the spindle 124 are housed within the inner housing 110. The inner housing 110 is housed within a front region of the body housing 101. A grip part 107 is arranged behind the front region of the body housing 101.
