Abstract: A separation preventing device that prevents separation of a fluid pipe in a pipe axis direction, includes a main body externally fitted to an outer peripheral surface of the fluid pipe and has a recess portion facing the outer peripheral surface; a locking member housed in the recess portion in a tiltable manner and is able to bite into the outer peripheral surface of the fluid pipe; a pressing member provided in the main body member and presses the locking member so as to bite into the outer peripheral surface of the fluid pipe; and an interposition member interposed between the locking member and the pressing member, wherein the interposition member is equipped with a tapered surface coming into contact with an outer surface of the locking member, and is housed in the recess portion in a state of having an acceptable movement value of a predetermined width in the pipe axis direction of the fluid pipe.

Abstract: An adhesive layer disposed between a separator for a secondary battery and an electrode for a secondary battery, wherein the adhesive layer is obtained by bonding under pressure a layer containing a resin having a structural unit derived from an ?-olefin having 2 to 4 carbon atoms, and an occupancy area of the resin in the adhesive layer is 10 to 80%.

Abstract: An adhesive resin composition for a secondary battery for bonding a separator for a secondary battery and an electrode for a secondary battery, wherein the composition comprises an adhesive resin having a unit derived from an aromatic vinyl monomer and having a glass transition temperature of 25° C. or lower.

Abstract: An adhesive resin composition for a secondary battery for bonding a separator for a secondary battery and an electrode for a secondary battery, wherein the composition comprises an adhesive resin, the adhesive resin contains the following (A) and (B), and the phase composed of (A) and (B) has a core shell heterophase structure and/or a sea-island heterophase structure: (A) a resin having a glass transition temperature of ?30° C. to +20° C., (B) a resin having a glass transition temperature 20° C. to 200° C. higher than the glass transition temperature of (A).
