Abstract
(EN)
An active material holding member 50a which is provided with a first tube 60 and second tube 61 arranged side by side, wherein: the first tube 60 is formed by having a base material 64 rolled up at least once in a counterclockwise direction; and a roll end part 66a of the base material 64 at one end of the first tube 60 is positioned within the range of from 0° to +90° on the surface of the first tube 60 with respect to the central axis of the first tube 60 if the direction in which the second tube 61 is arranged with respect to the first tube 60 is taken as 0° when the first tube 60 is viewed from the above-described one end side of the first tube 60 in the axial direction of the first tube 60.
(FR)
L'invention concerne un élément de maintien de matériau actif 50a comportant un premier tube 60 et un second tube 61 disposés côte à côte, le premier tube 60 étant formé en ayant un matériau de base 64 enroulé au moins une fois dans le sens inverse des aiguilles d'une montre ; et une partie d'extrémité de rouleau 66a du matériau de base 64 à une extrémité du premier tube 60 est positionnée dans la plage de 0° à +90° sur la surface du premier tube 60 par rapport à l'axe central du premier tube 60. Si la direction dans laquelle le second tube 61 est disposé par rapport au premier tube 60 est prise comme 0° lorsque le premier tube 60 est vu depuis le côté d'extrémité décrit ci-dessus du premier tube 60 dans la direction axiale du premier tube 60.
(JA)
互いに併設された第1のチューブ60及び第2のチューブ61を備える活物質保持部材50aであって、第1のチューブ60が、基材64が反時計回りに少なくとも一周巻き回されることにより形成されており、第1のチューブ60の一端における基材64の巻き端部66aが、第1のチューブ60の軸方向に第1のチューブ60の前記一端側から第1のチューブ60を見たときに、第1のチューブ60に対する第2のチューブ61の併設方向を0°として、第1のチューブ60の中心軸に対して第1のチューブ60の表面における0°以上+90°以下の範囲に位置する、活物質保持部材50a。
