摘要： A compact and light-weight portable electric router produced at a low cost and capable of providing high cutting efficiency with low noise. A radial fan includes a cylindrical hub functioning as an attachment portion to a motor shaft, a plurality of fan blades having parts connecting to the hub, and a ring like guide section connected to the hub through the fan blades. An annular weight is connected to the guide section at a radially outer side of the guide section. The weight serves as a restriction section for restricting backflow of air from a discharge side to a motor side.

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 power tool providing a smooth cooling air flow discharging through discharge windows formed in a housing. In the housing a radial fan is rotatably provided for cooling a heated motor. A cooling air generated by the radial fan is discharged through the discharge windows. Each discharge window has a rectangular shape having an upstream side and a downstream side in the rotating direction of the cooling fan. A chamfered portion is provided at least at the upstream side and in an inner peripheral surface of the housing, so that a thickness of the housing wall is gradually small in the rotating direction. The chamfered portion increases an effective area of the window for discharging air.

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.
