Abstract: front page image
(EN)According to the present invention, an armature 32has a fixed part 32a, an extending part 32b, a bent part 32c, and a movable part 32d. The moveable part 32d of the armature 32 is inserted into a coil 27 to face magnets 24, 25, and the fixed part 32a overlaps an outer surface 21b of a yoke 21. Two edge parts 32f, 32f of the fixed part 32a and the outer surface 21b of the yoke 21 are subjected to laser spot welding to form welded parts 51, 51, 52, 52 in four locations.
(FR)La présente invention concerne une armature (32) ayant une partie fixe (32a), une partie d'extension 32b, une partie courbée (32c) et une partie mobile (32d). La partie mobile (32d) de l'armature (32) est insérée dans une bobine 27 pour faire face à des aimants (24, 25), et la partie fixe (32a) chevauche une surface externe (21b) d'une culasse (21). Deux parties de bord (32f, 32f) de la partie fixe (32a) et la surface externe (21b) de la culasse (21) sont soumises à un soudage par points laser pour former des parties soudées (51,51,52, 52) à quatre emplacements.
(JA)アーマチュア32は、固定部32aと延出部32bと曲げ部32cおよび可動部32dを有している。アーマチュア32の可動部32dをコイル27の内部に挿入して磁石24,25に対向させ、固定部32aをヨーク21の外面21bに重ねる。固定部32aの2つの縁部32f,32fとヨーク21の外面21bとをレーザースポット溶接して、4か所の溶接部51,51,52,52を形成する。
