摘要： A flux-cored wire for gas-shielded arc welding comprises a steel sheath, and a flux filled in the steel sheath. The flux-cored wire has a C content of 0.20% by mass or below, a Si content in the range of 0.06 to 1.10% by mass, a Mn content in the range of 0.55 to 1.60% by mass, a Cr content of 2.60% by mass or below, a Mo content in the range of 0.30 to 1.50% by mass, a Mg content in the range of 0.20 to 1.50% by mass, a N content in the range of 0.005 to 0.035% by mass and a B content in the range of 0.001 to 0.020% by mass on the basis of the total mass of the flux-cored wire. The flux has a TiO2 content in the range of 4.2 to 8.2% by mass and a fluorine compound content in terms of F content in the range of 0.025 to 0.55% by mass on the basis of the total mass of the flux-cored wire, and the flux-cored wire has an Al content of 0.50% by mass or below, a Nb content of 0.015% by mass or below, and a V content of 0.015% by mass or below on the basis of the total mass of the flux-cored wire. The flux-cored wire forms a weld metal that is resistant to ferrite band maintains proper tensile strength and excellent toughness even if the weld metal is processed at high temperatures for a long time for PWHT. The flux-cored wire has satisfactory usability

摘要： A vehicle rotary electric machine to be mounted in an engine is comprised of a rotor having a shaft, a stator, a front housing, a rear housing and a pulley. The front housing has a first mounting stay disposed at a side of the front housing to be fixed to a cylinder block of an engine by a bolt and a second mounting stay disposed at the opposite side of the front housing with respect to the shaft to be fixed to a cylinder head of the engine by a bolt having the same outside diameter. The rear housing has a third mounting stay to be fixed to the cylinder head at the same side of the rear housing as the second mounting stay. The first mounting stay has an elliptical first bolt-hole extending perpendicularly to the stack direction. The a major axis of the elliptical hole extends in parallel to the stack direction.
