Abstract: A packaging material for a power storage device includes a base material layer which has at least a first adhesive layer, a metal foil layer, a corrosion prevention-treated layer, a second adhesive layer, and a sealant layer, sequentially laminated on the side of the first surface thereof; and a base material protective layer formed from at least one selected from the group consisting of a polyester polyol and an acrylic polyol, each containing a group having a hydroxyl group in a side chain thereof, and an aliphatic isocyanate curing agent, laminated on the side of the second surface of in the base material layer.

Abstract: A packaging material for a power storage device having a laminate structure in the following order including a substrate layer, a first adhesive layer, a metal foil layer, a second adhesive layer, and an inner layer containing a polyester-based resin. The inner layer has a melting peak temperature during melting in a range of 160 to 280° C. which is measured by a differential scanning calorimeter. The substrate layer has a melting peak temperature that is higher than the melting peak temperature of the inner layer.

Abstract: A packaging material for a power storage device of the present invention includes: a base layer having a first surface and a second surface, the first surface having at least a first adhesive layer, a metal foil layer, an anticorrosive treatment layer, a second adhesive layer, and a sealant layer laminated thereon in this order; and a base protective layer laminated on the second surface of the base layer, and formed containing at least one base resin selected from a group consisting of a polyester polyol and an acrylic polyol, each of which has a group having a hydroxyl group on a side chain, and a curing agent containing at least one of a biuret type and an isocyanurate type of isocyanate.

Abstract: A power storage device packaging material includes: a base material layer; a metal foil layer formed on one surface of the base material layer via an adhesive layer; and a sealant layer arranged on a surface of the metal foil layer, the surface of the metal foil layer being on the opposite side to the base material layer, wherein the base material layer contains a polyester resin that contains a polyester elastomer and/or an amorphous polyester.

Abstract: When an assembly in which a sprag is temporarily assembled to a retainer by a return spring is assembled between an outer race and an inner race, even if the sprag projecting from the retainer is depressed, a drop-out of the sprag is prevented by a retaining member of a friction plate fixed to the end portion of the retainer. A lubrication passage is formed by opening a space surrounded by the outer race, retainer, and sprag to the outer peripheral side. An attaching member of the friction plate which is fixed to the retainer by a spot welding is recessed backward by joggling in a downward stairway manner for a contact surface. Therefore, even if a rise occurs in the attaching member by the welding, the rise is not come into contact with the contact surface.
