Abstract: An electrical connector includes an insulating housing having an annular recess extending rearwardly from a front end thereof and a shield member having a cylindrical wall fitted into the annular recess, a plurality of contact lugs extending outwardly in radial directions from a front edge thereof, and a leg member for connection with a shield circuit of a printed circuit board. The shield member has a plurality of first cantilever contacts bent outwardly and then inwardly forming an outward projection for contact with a metal shield provided on an inside of a mating shell member and a plurality of second cantilever contacts bent inwardly and then outwardly forming an inward projection for contact with a metal shield provided on an outside of the mating shell member.

Abstract: Disclosed is an air cooled internal combustion engine which comprises a cooling fan formed unitarily on a flywheel fixed to one end of an engine crank shaft, a cooling fan case covering the cooling fan and adapted to guide the flow of cooling air generated by the cooling fan toward the engine body, an air cleaner connected to the suction port of the engine, and a silencer connected to the exhaust port of the engine, wherein the suction port is located at the same side of the engine body as the flywheel while the other exhaust port is located at the opposite side of the engine body to the flywheel, and wherein the air cleaner is formed integrally with the cooling fan case.
