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.
摘要翻译：在火花塞的点火点和点火地之间发生火花。火花塞从火花塞芯的一个急剧拐角射出。芯的尖端具有不大于45度的锐角。通过这种布置，火花的发射点可以集中到芯的尖端。为了降低点火地的热容量以提高点火性，与点火地面的火花放置面相对的一侧是锥形的，以提供角度。此外，点火地具有提供不超过45度的角度的顶端。由于顶点部分，可以减少点火地面的热容量，并且可以实现锐角以将火花塞接收点集中在顶部。因此，可以提高点火性。

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： 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.
