The grease is excellent in low-temperature performance and has low oil separation tendency. In particular, when used in a rotation transmission device having a built-in one-way clutch, the grease can provide satisfactory clutch engagement performance (intermeshing) at low temperatures and is less apt to cause oil separation under high centrifugal force.

Abstract: A grease which comprises a base oil containing at least 50% by mass of a diester compound having a total carbon number of 28 to 40 and represented by the general formula (I): R1OOC—(R2)n—COOR3??(I) wherein R1 and R3 each independently represent a C4 to C20 monovalent aliphatic hydrocarbon group, R2 represents a C1 to C20 divalent hydrocarbon group and n is 0 or 1. The grease is excellent in both low-temperature performance and high-temperature performance and has low oil separation tendency even under high centrifugal force (acceleration). In particular, when the grease is used in a rotational transmission device having a built-in one-way clutch, the grease can provide satisfactory clutch engagement property (intermeshing ability) at low temperatures and a prolonged bearing life at high temperatures and is less apt to cause oil separation under high centrifugal force.

Abstract: A resistance welding structure and a resistance welding method may form a highly reliable welded part by applying a proper pressurizing force and a proper heat value to a joining portion. Also provided are a member to be welded which is suitable for carrying out these resistance welding structure and resistance welding method, and a method of manufacturing the member to be welded. A member to be welded is formed with a recessed portion on one surface of a raw material formed of a metal plate, and a projection is formed on a back surface of the recessed portion. Assuming a plate thickness of the raw material in the inside of the recessed portion and around the periphery of the projection as D2, and a plate thickness of the raw material outside the recessed portion 2 as D3, the plate thicknesses of the respective portions have the relationship of D2<D3.

Abstract: A convex portion which inclines in the direction of the short side is created by press work along the direction of the short side of a terminal, which extends longitudinally, from one end to the other end, and another terminal is pressed onto the convex portion with pressure and bonded together by electric resistance welding. At this time, because the convex portion inclines in the direction of the short side, the convex portion is not deformed and crushed; consequently, it is possible to ensure the area of the contact at which terminals are bonded together.
