Abstract: A stratified scavenging two-stroke engine includes a first scavenging passage that extends from a first scavenging intake that opens to the inside of the crankcase to a first scavenging port that opens to the inside of a cylinder, and a second scavenging passage that extends from a second scavenging intake that opens to the inside of the crankcase to a second scavenging port that opens to the inside of the cylinder. The first and second passages are formed so as to communicate with each other via a communicating portion. An air passage is connected to the first passage at a position closer to the first scavenging intake than the communicating portion. A first check valve inhibits a flow from the first passage to the inside of the crankcase, and a second check valve inhibits a flow from the first passage through the air passage to the outside.

Abstract: An electric tool, such as an angle driver, has a main tool body with a front portion and a rear portion positioned opposite to the front portion. The main tool body houses a motor configured to receive electricity to function as a drive source. A gear head is coupled with the front portion of the main tool body wherein the gear head has a spindle in communication with a motor axis of the motor via mesh-engagement of bevel gears associated with the motor axis. The spindle has with a cutter tool accessory attached thereto such that rotation of the motor axis produces a commensurate rotation of the cutter tool accessory. Battery attachment portions are associated with the rear portion of the main tool body and are configured to receive a corresponding set of batteries that provide electricity to power the motor.
