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 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.

摘要： A combustion-type power tool includes a cylinder and a combustion chamber frame disposed to surround the cylinder and movable along the cylinder. A partition wall divides an inner space of an outer frame into a first space in which the cylinder and the combustion chamber frame are disposed and a second space in which a gas cartridge cylinder is disposed and has a through-hole through which the first space and the second space are in fluid communication with each other. A plurality of ribs is formed on an outer surface of the cylinder for regulating an exhaust gas flow generated by combustion of a gaseous mixture in the combustion chamber. The ribs enable exhaust gas discharged from the combustion chamber to be directed away from the through-hole, thereby enabling the gas cartridge cylinder to be maintained at a substantially constant temperature.
