摘要： PROBLEM TO BE SOLVED: To obtain sufficient fixing strength even in a thin denture attachment by freely attachably and detachably mounting a magnet structure body attached to the base side of an artificial tooth by magnetic attraction force to a plate to be attracted which is implanted in the dental root part and constituting this structural body of an annular magnet body and the yoke part enclosing this magnet body. SOLUTION: The denture 11 comprises a dental plate 12, the artificial tooth 13 disposed in this dental plate 12 and the magnet structure body 14 attached by fixing means to the base side of the artificial tooth 13. The plate 15 to be attracted which consists of a soft magnetic alloy previously disposed in the dental root is attracted by the magnetic attraction force to the magnet structural body 14 and is thereby freely attachably and detachably fixed into the dental root. The magnet structural body 14 comprises the annular magnet body 16 intersecting with a tooth height direction A and the yoke part 17 enclosing the magnetic body 16 so as to embed its central hole. The yoke part 17 comprises a crowned yoke 18 having an annular housing groove corresponding to the magnet body 16 and an annular cap yoke 19 for sealing the magnet body 16 into this housing groove.

摘要： PROBLEM TO BE SOLVED: To provide a direct drive-type motor-driven wheel, for a low-speed motor car, which restrains an increase in the body structure and the weight of a motor and which enhances a torque. SOLUTION: A direct drive-type motor-driven wheel which has a motor structure of an outer rotor type is provided with a brushless DC motor which has a permanent magnet-type field core 1. Respective phase coils at a stator coil (preferably a three-phase stator coil) 4 are concentrated and wound individually and sequentially on respective pole teeth at a stator core. Thereby, as compared with a case in which the three-phase stator coil 4 is dispersed and wound, a starting torque and a low-speed torque can be enhanced sharply. As a result, the low-speed running performance of the direct drive-type motor- driven wheel which is provided with the brushless DC motor can be greatly enhanced.

The traverse cross section of the yoke 2 is formed in U-shape, and it is composed of mutually opposing wall parts 21 and 22 and an interconnected wall part 25. A mixed material, consisting of rare-earth magnet powder and resin, is put in between the opposing wall parts 21 and 22 of the yoke 2, and a resin magnet part 4 is formed. A magnetic path P1, which passes the opposing wall part 22 on the outer circumferential side of the attachment 1, and the magnetic path P2, which passes the opposing wall part 21 on the inner circumferential side of the attachment 1, are endlessly formed corresponding to the endlessly shaped yoke 2 when viewed in horizontal state of the attachment 1.
