Abstract:
(EN) Provided is a motor that includes a bearing holder and a first bearing. The bearing holder is fixed to a casing. The first bearing is interposed between the bearing holder and a shaft. The bearing holder includes a resin holder body and a metal ring member. The holder body includes, around a center shaft, a first arc-shaped part that has one or a plurality of through holes that pass through in the axial direction, and a second arc-shaped part that does not have a through hole. The first arc-shaped part covers a range of one third or more in the circumferential direction. The outer ring of the first bearing is held by the ring member.
(FR) La présente invention concerne un moteur qui comprend un support de palier et un premier palier. Le support de palier est fixé à un boîtier. Le premier palier est interposé entre le support de palier et un arbre. Le support de palier comprend un corps de support en résine et un élément annulaire métallique. Le corps de support comprend, autour d'un arbre central, une première partie en forme d'arc traversée dans la direction axiale par un ou plusieurs trous traversants, et une seconde partie en forme d'arc qui n'a pas de trou traversant. La première partie en forme d'arc couvre une plage d'un tiers ou plus dans la direction circonférentielle. La bague extérieure du premier palier est maintenue par l'élément annulaire.
(JA) モータは、ベアリングホルダと第1ベアリングとを有する。ベアリングホルダは、ケーシングに固定される。第1ベアリングは、ベアリングホルダとシャフトとの間に介在する。ベアリングホルダは、樹脂製のホルダ本体と、金属製のリング部材と、を有する。ホルダ本体は、中心軸の周囲に、軸方向に貫通する1つまたは複数の貫通孔を有する第1弧状部と、貫通孔の無い第2弧状部と、を有する。第1弧状部は、周方向の1/3以上の範囲を占める。第1ベアリングの外輪は、リング部材に保持される。
