Abstract: An auxiliary base further improves the stability of a jigsaw during cutting as appropriate. An auxiliary base is attachable to a jigsaw. The jigsaw includes a base unit to be in contact with a workpiece, and a body tiltable relative to the base unit in a lateral direction. The auxiliary base includes a contact portion to be in contact with the workpiece when the auxiliary base is attached to the jigsaw. The auxiliary base is attachable with an auxiliary width from the contact portion to a middle of the base unit in the lateral direction of the body being greater than a width of the base unit in the lateral direction.

Abstract: A lifter device includes: a pole; a lifting member configured to be guided by the pole; a motor configured to generate power used for ascending and descending of the lifting member; a transmission mechanism configured to transmit the power of the motor to the lifting member; and a preventing member configured to prevent the descending of the lifting member when the power is not transmitted.

Abstract: A cutting machine includes a base having an abutment surface, a cutting machine body and at least one tilt support part that supports the cutting machine body such that the cutting machine body can be tilted relative to the base around a first axis. The at least one tilt support part includes a tilt plate fixed to the cutting machine body, an angular plate arranged to face the tilt plate and fixed to the base, and a link arm configured to connect the tilt plate and the angular plate. When the cutting machine body is tilted, the tilt plate tilts together with the cutting machine body, and facing surfaces of the tilt plate and the angular plate slide in contact with each other, and the link arm tilts around a second axis parallel to the first axis in interlocking with tilting of the cutting machine body.

Abstract: An attachment structure for attaching an auxiliary fitting such as a parallel ruler to a portable machining apparatus allows simpler assembly and maintenance. A portable machining apparatus includes a base having a lower surface to be in contact with a workpiece, a machining body supported on an upper surface of the base, and a mount that receives an auxiliary fitting removably attachable to the base. The mount includes an internal threaded fastener detachably supported on the base, an external threaded fastener screwed with the internal threaded fastener to be tightened with the internal threaded fastener to press the auxiliary fitting onto the base, and a locking section that locks the external threaded fastener with respect to the internal threaded fastener.

Abstract: A bracket (20) includes: a pedestal (21, 22) that is mountable on a support frame (2) of a work stand (1) for supporting a saw (60); and first and second engaging parts (38A, 38B) arranged on the pedestal to sandwich the support frame in a horizontal direction and engage with first and second engagement parts (8A, 8B) on opposite sides of the support frame. The second engaging part includes first and second levers (41, 42). The pedestal is movable along the longitudinal direction of the support frame by manipulating only the first lever to disengage it from the second engagement part (8B) and is removable from the support frame by simultaneously manipulating both the first and second levers in the same direction to disengage them from the second engagement part. The first and second levers both move in the same opposite direction to engage the second engagement part.

Abstract: An operation knob is attached to one end of a transmission rod. The transmission rod is located in a slide bar supporting a cutting device main body so as to be slidable in a front-to-rear direction. A pulley of a belt transmission mechanism is joined to the other end of the transmission rod, and a click mechanism is arranged around a portion of the pulley. The click mechanism provides a tactile sensation (e.g. click feeling or feeling of moderation) and improves operability of the operation knob.

Abstract: A cutting device may include a friction reducing device arranged in an operational force transmission path between an operation member and a fixing device that can fix a circular cutter to a rotational shaft of a cutting unit.

Abstract: An interposing member is interposed between a base part of the fence plate and a top plate part of a base, and a position of the fence plate is changed on the interposing member. Because of this, deflection etc. of the top plate can be reduced and variation of an operating angle of an operating lever can be reduced when fixing the fence plate to the base.

Abstract: A cutting machine includes a housing accommodating a motor. In the housing, a cutting blade, an air duct, a dust collecting channel and a shutter member are provided. The cutting blade is operated with the driven motor to cut a workpiece, and the air duct allows cooling air generated by a cooling fan for the motor to be blown out onto a cutting place of the workpiece. The dust collecting channel has an opening at one end for serving as a dust collecting port located near the cutting place and an opening at the other end for permitting coupling of a dust collecting nozzle. The shutter member is movable between a closed position and an open position of the air duct and located in the open position in a normal state.
