Abstract: Provided is a cylindrical battery (10) comprising an outer covering can (16) which is in a bottomed cylindrical shape and accommodates an electrode body (14) and a sealing body (17) which closes an opening portion of the outer covering can (16), the sealing body (17) includes a current-collection plate (25) and a cap (26) which is placed on and secured to the current collection plate (25), and the current collection plate (25) includes a securing means which secures the outer peripheral portion of the cap (25).

Abstract: A sealed battery that is an example of an embodiment comprises: an electrode assembly; an outer housing can that houses the electrode assembly; and a sealing assembly that closes an opening of the outer can. The sealing assembly includes: a cap; and a current collector plate that is located closer to the electrode assembly than the cap and that is welded to the cap. The current collector plate has, in a portion thereof welded to the cap, a recess protruding toward the cap.

Abstract: A tire constituting member in an unvulcanized tire having a joint portion is prevented from being triply overlapped and is wound around a body to be formed. When detecting the joint portion, the tire constituting member is cut into a length shorter than a predetermined length while excluding the joint portion. A front end and rear end portions of the wound tire constituting member are held by front and rear end holding members. The tire constituting member is extended into a predetermined length and both holding members are moved to the side of the body. The front end portion is attached to the body, a support member is rotated, the tire constituting member is wound around the body, the rear end holding member is moved to the side of the body as the tire constituting member is wound and the rear end portion is joined to the front end portion.
