Abstract: The power generator includes: an alternator for generating electricity by driving an engine; an inverter case containing an inverter circuit of the alternator; a fuel tank for storing a fuel to be supplied to the engine; and a casing for housing at least the engine, the alternator and the inverter case, wherein the inverter case and the fuel tank are formed of a material having higher thermal conductivity than the casing, and the inverter case is disposed in contact with the fuel tank.

Abstract: A charging cable support arm includes a support member that is fixed to a wall face, a first arm whose proximal end portion is hinged to the support member and that is rotatable within a horizontal plane, and a second arm that is hinged to a distal end of the first arm and that is rotatable within a horizontal plane. The first arm is provided with a first passage hole through which a charging cable is inserted into the first arm, and the second arm 3 is provided with, at a distal end thereof, a fourth passage hole from which the inserted charging cable is pulled out, and by use of the charging cable pulled out of the fourth passage hole, an electric vehicle is charged.

Abstract: A charging cable support arm includes a support member 1 that is fixed to a wall face, a first arm 2 whose proximal end portion is hinged to the support member 1 and that is rotatable within a horizontal plane, and a second arm 3 that is hinged to a distal end of the first arm 2 and that is rotatable within a horizontal plane. The first arm 2 is provided with a first passage hole 24a through which a charging cable 40 is inserted into the first arm 2, and the second arm 3 is provided with, at a distal end thereof, a fourth passage hole 34b from which the inserted charging cable 40 is pulled out, and by use of the charging cable 40 pulled out of the fourth passage hole 34b, an electric vehicle M is charged.

Abstract: A cogeneration apparatus for indoor installation includes: an airtight chamber provided within a housing, at least a power generator and an engine being accommodated within the airtight chamber; an intake duct connected to the airtight chamber for introducing air from outside the housing into the airtight chamber; and an exhaust duct connected to the engine for discharging exhaust gas of the engine. The air introduced through the intake duct cools the interior of the airtight chamber and is also sucked in to an air cleaner of the engine, and the exhaust gas of the engine is discharged directly to outside the airtight chamber through the exhaust duct.
