Abstract:
(EN) Provided is a bellow that has exceptional durability. An abdomen-shaped bellow 10 in which cross-sectionally U-shaped peak parts 10A and cross-sectionally U-shaped trough parts 10B are repeatedly formed with abdomen parts 20, 30 in between, wherein both abdomen parts 20, 30 joined to the peak parts 10A are each configured from a first section α, a second section β, a third section γ, and a fourth section δ leading smoothly in order from the side with the peak part 10A toward the adjacent trough parts 10B, 10B, and in a freely elongated state of the bellow 10, the separating distance between second sections β is longer than that between the first sections α and between the third sections γ of both of the abdomen parts 20, 30 (h2 > h1, h3).
(FR) L'invention concerne un soufflet qui présente une durabilité exceptionnelle. L'invention concerne un soufflet en forme d'abdomen (10) dans lequel des parties de crête en forme de U de section transversale (10A) et des parties de creux en forme de U de section transversale (10B) sont formées de façon répétée avec des parties d'abdomen (20, 30) entre elles, les deux parties d'abdomen (20, 30) raccordées aux parties de crête (10A) étant chacune configurées à partir d'une première section α, d'une deuxième section β, d'une troisième section γ et d'une quatrième section δ menant sans à-coups dans l'ordre du côté comprenant la partie de crête (10A) aux parties de creux adjacentes (10B, 10B), et dans un état librement allongé du soufflet (10), la distance de séparation entre les deuxièmes sections β est plus longue que celle entre les premières sections α et entre les troisièmes sections γ des deux parties d'abdomen (20, 30) (h2 > h1, h3).
(JA) 耐久性に優れるベローズを提供する。 断面U字状の山部10Aと断面U字状の谷部10Bとが腹部20,30を介して繰り返し形成される腹形状のベローズ10であって、前記山部10Aに繋がる両方の前記腹部20,30は、該山部10A側から隣接する前記谷部10B,10Bに向けて順に円滑に連なる第1部位α、第2部位β、第3部γ位及び第4部位δから構成されており、前記ベローズ10の自由長状態において、両方の前記腹部20,30の前記第1部位α間及び前記第3部位γ間よりも前記第2部位β間の離間距離が長い(h2>h1,h3)。
