摘要： A combustion-type nail driver uses a motor for driving a fan. A motor holder formed from plastic accommodates the motor. A cylinder head has a motor holder receiving portion in which the motor holder is slidably movably disposed. A coil spring has one end secured to the motor holder and another end secured to the cylinder head to thereby support the motor holder. Initial acceleration applied to the motor when combustion occurs can be suppressed and impact imparted upon the motor can also be suppressed by friction between the outer periphery of the motor holder and the inner periphery of the motor holder receiving portion. A heat shielding plate is interposed between the lower end surface of the motor and the cylinder head in order to prevent hot air combustion gas from entering into the motor.

摘要： A dust collection cover capable of efficiently collecting cutting chips and residues generated as a result of cutting a workpiece. A cutter includes a motor and a rotary blade driven by the motor, and the dust collection cover is attached to the cover for covering a part of the blade. The cover is formed with a dust discharge port through which cutting chips and residues are discharged. The cover has a guide arrangement for directing the cutting chips and residues toward an interior of the cover body. The arrangement provides a blowing-out air blowing to the workpiece, or a rod-like member removing the cutting chips and residues.

摘要： In the combustion-type power tool, a first shelter wall and a second shelter wall are disposed to partially surround an area between an ignition plug and an ignition ground. Two gaps are provided between the first and second shelter walls. The first shelter wall extends radially outwardly from an outer peripheral surface of a motor boss, and also protrudes from an end face in an axial direction of a fan shaft. The first shelter wall has a lower end surface inclined such that an axial length between the end face and the lower end surface is gradually reduced toward radially outer end of the first shelter wall.

摘要： A spark is shot between an ignition point of an ignition plug and an ignition ground. The spark is shot from an acute corner of a core of the ignition plug. A tip end of the core has an acute angle of not more than 45 degrees. With this arrangement, an emitting point of the spark can be concentrated to the tip end of the core. In order to reduce a thermal capacity of the ignition ground so as to enhance ignitability, a side opposite to the spark seating face of the ignition ground is tapered to provide an angle. Further, the ignition ground has an apex end providing an angle which is not more than 45 degrees. Because of the apex portion, thermal capacity of the ignition ground can be reduced and an acute angle can be realized to concentrate spark receiving point at the apex portion. As a result, ignitability can be enhanced.

摘要： A combustion type power tool having a combustion chamber in which a fan is rotatably provided and an ignition plug is exposed. A combustible gas and air are mixed together by the fan, and the mixture is ignited by a spark generated at the ignition plug. As a result of combustion, gas expansion occurs to permit a piston and a driver blade to move for driving a fastener into a workpiece. A spark energy is set in a range of from 0.04 J to 0.08 J.

摘要： A combustion-type power tool capable of preventing a sub-stream of air-fuel mixture from passing through a gap between an electrode and an opposing electrode section, and yet capable of providing a desirable ignition without lowering maintenance efficiency of the tool. The opposing electrode section opposes the electrode of an ignition plug body. A head cap supports the opposing electrode section at a position closer to an axis of a fan than the electrode to the axis. The opposing electrode section protrudes from the head cap outward in the radial direction of the fan. The side of the head cap defining a combustion chamber has three parts. A first part surrounds the rotation axis of the fan. A second part supports the ignition plug body. A third part located in the radially outer side of the second section with respect to the axis.
