Abstract: A power storage device includes an electrode stack including a plurality of electrodes, a separator, and a resin sealing portion. The plurality of electrodes include a bipolar electrode. The bipolar electrode includes a current collector, a positive electrode active material layer, and a negative electrode active material layer. The sealing portion includes a first adhesive portion adhered to the current collector, a second adhesive portion adhered to the current collector, a first reinforcing portion bonded to the first adhesive portion, a second reinforcing portion bonded to the second adhesive portion, and an end surface welded portion. A water vapour transmission rate of the end surface welded portion is less than a water vapour transmission rate of the first adhesive portion and a water vapour transmission rate of the second adhesive portion.

Abstract: A headrest comprising a pad member that includes a recess shaped housing portion open to a rear side when the headrest is assembled to a vehicle seat and that is a resilient body that supports the head of an occupant; and an attachment member that has a portion housed in the housing portion, that is formed with an opening portion for attaching a display device to, and that further has an outer peripheral portion of the opening portion that is disposed further to the rear side than the pad member.

Abstract: There is provided a headrest including a main body member, a stay member, and a stopper member, the stopper member including a circular cylinder shaped circular cylinder portion, a cantilevered portion, a projection portion, and a restriction portion that is formed extending from the circular cylinder portion so as to abut an end portion of a support member when an attempt is made to pull the stay member out from the support members in a projecting state in which both end sides of the stay member are inserted into the support member and project out from end portions of the support members, thereby restricting pulling out of the stay member from the support members.

Abstract: This discloses a novel human or rat polypeptide useful in improving and/or preventing organ fibrosis and a polynucleotide encoding the aforementioned polypeptide, an expression vector containing the aforementioned polynucleotide, and a cell transfected with the aforementioned expression vector. The aforementioned polynucleotide shows a remarkable decrease in the expression dose in the kidney of a chronic renal insufficiency model rat and in the bladder of a rat suffering from the induction of fibrotic conditions in the bladder, compared with a normal individual. Also, the production of extracellular matrix is suppressed by overexpression of the aforementioned polypeptide. Also disclosed are the promoter region of the aforementioned polypeptide, a method for screening a remedy for fibrotic conditions, and a process for producing a medicinal composition for improving fibrotic conditions which contains a substance obtained by the aforementioned screening method as the active ingredient.
