Abstract: Disclosed is a rotation angle detecting device wherein a filling member applied in a second housing section which houses an electromagnetic conversion element is prevented from entering a first housing section which houses a magnet.

Abstract: A position detecting device affixed to a handle bar, wherein the positional displacement between a section to be detected and a detecting section is minimized to reduce the degradation of the detection accuracy. A position detecting device 1 comprising: a section 4 to be detected which is rotated on the basis of the rotational operation of a handle grip 3 provided to a handle bar 2; a detecting section 5 which detects the section 4 to be detected; and a case 6 which contains the section 4 to be detected and the detecting section 5, wherein the position detecting device 1 is also provided with a support member 7 which rotatably supports the section 4 to be detected and to which the detecting section 5 is affixed.

Abstract: Provided is a position detector device capable of suppressing the effect of external magnetic fields on precision in detection. A position detector device (1) comprises: a subject to be detected (4a), which rotates along with the rotation of a handle grip (3) that is disposed on a handlebar (2); a detector unit (5) that detects the subject to be detected (4a); and a case (7) which houses the subject to be detected (4a) and the detector (5). The subject to be detected (4a) is treated as a magnetic cylindrical body, the detector unit (5) is treated as a magnetic detector unit (5) that detects changes in magnetism. A support member (6) rotatably supports the subject to be detected (4a), and further comprises a housing member (65) that houses the detector unit (5) on the interior circumference side of the subject to be detected (4a).

Abstract: A rotation detector that can be assembled into a hub of a wheel without breakage of an object to be detected. The rotation detector has a housing (1) having an insertion section (1a) in which an axle (S) is inserted and that is placed between a hub (10a) of a front wheel (10) and a front fork, a magnet (3a) placed in the housing (1) and generating a magnetic field, and a magnetism detection element (3) provided in the housing (1) so as to be able to detect a change in the magnetic field and detecting the change in the magnetic field involved in the rotation of the object (5) to be detected. The object (5) to be detected is formed of a different magnetic material from the hub (10a) and has a portion (5a) to be detected that rotates in synchronous with the hub (10a).

Abstract: A stepping motor type indicator provided with unambiguous stable points having a holding force in a non-excited condition sufficient to suppress undesirable movements of a pointer. The stepping motor type indicator includes a stepping motor (2) having a rotor (28) with an output shaft (27) and stators (A, B). Yokes (23, 26) have a plurality of pole teeth (232, 233, 262, 263) extending toward curved outer surfaces of the rotor. The pole ends of a specific pole tooth (232a) chosen from one of the plurality of pole teeth is made to have a pole end area different than that of the remaining pole teeth. This structure produces unambiguous stable points (“a”-“l”) and produces strong holding forces so that an attractive force exerted by the stable point (“a”) on the pointer (4) toward stopper pin (7) is increased to positively suppress undesirable movements of pointer (4).
