PROBLEM TO BE SOLVED: To solve the problem that various members are requested to be thinner and lighter from a view point of COreduction and further special carts such as a food cart and a medical cart are requested to have an antirust property as well, which makes it difficult to alternate a present cart with a new cart.SOLUTION: A channel-like main base member, which constitutes a part of a main base part, has a channel-like cross section and has opposing lip parts on both sides thereof, is covered with a side base member from below, and a bridge-plate member acting as a plate spring is placed on the lip parts on both sides and fastened by bolt-nut fastening. The base member can be constituted of martensitic stainless steel containing niobium that is thin and has an antirust property and does not become an obstacle because a bolt and a nut are not exposed, which therefore can be applied to a special cart as well.
【課題】最近では、CO2削減の観点からも、各種部材に薄肉軽量化の要求が強くなっているが、食糧台車や薬用台車用等の特殊な台車「では防錆性も要求されており、現行品の代替は簡単ではない。【解決手段】メインベース部の一部を成す、断面がチャンネル状で両側のリップ部が対向するチャンネル状メインベース部材に、サイドベース部材を下側から被せると共に、両側のリップ部に板バネとして作用する渡し板部材を載せ、ボルトナット締結により締付け固定する。ベース部材を、薄肉で防錆性もあるニオブ含有マルテンサイト系ステンレス鋼で構成でき、ボルトやナットも表に出ないので、邪魔にはならず、特殊な台車にも適用できる。【選択図】 図5
