摘要： PROBLEM TO BE SOLVED: To provide a rotary angle detector without problems caused by errors in index signals due to influence of an adjacent magnetic rotary angle generation part within the angle range of an index magnetic flux density detecting element (such as a Hall element embedded in a Hall IC for generating an index signal) against an index non-magnetic part.
SOLUTION: A magnetic angle of a north/south poles magnetic part of an index magnetic part β is set to become larger than a magnetic angle of a north/South poles magnetic part of a rotary angle magnetic part α, and a south pole magnetic part of the index magnetic part β is overlapped on a north pole magnetic part of the rotary angle magnetic part α. Due to the overlap, when an index Hall IC faces to an index non-magnetic part β', a magnetic flux of the north pole applied to the index Hall IC by the north pole magnetic part of the rotary angle magnetic part α can be neutralized by a magnetic flux of the south pole magnetic part of the index magnetic part β, and thereby no index signal is generated by the index Hall IC.

摘要： PROBLEM TO BE SOLVED: To solve the problem wherein the probability of generating a malfunction of an index magnetic flux density detection element 62Z under the influence of the N-pole of adjacent rotation angle magnetizing part α, within an angle region wherein the detection element 62Z faces the index non-magnetizing part β', in a device which generates index signals, when the detection element 62Z is imparted with N-pole magnetic flux. SOLUTION: The index magnetizing part β is offset to the S-pole side. When the index magnetic flux density detection element 62Z is within the angle region, wherein the detection element 62Z faces the index non-magnetizing part β', even if the magnetic flux of the N-pole is imparted to the element 62Z, the N-pole magnetic flux imparted to the detection element 62Z from the rotation angle magnetizing part α is canceled by the S-pole (strength of the S-pole is reinforced by means of the offset magnetization). As a result, the problem that the detection element 62Z generates the N-pole side signal under the influence of the rotation angle magnetization part α, is solved and the malfunction never occurs.

摘要： PROBLEM TO BE SOLVED: To solve such a problem that a conventional rotary angle detector has a too long distance x' between a magnetic flux detecting area J7 and a magnet J2, because of providing a potting J6 protecting a fluctuation of magnetic flux detecting means J3 protecting from flying oil splash or metal powder. SOLUTION: By adopting a constitution of rotary angle detector that a magnetic flux detecting means 52 is arranged on the other side of a board 53 facing to a magnet 51, a potting can be eliminated because the magnetic flux detecting means is protected by the board 53 from the flying oil splash or metal powder, therefore the distance x between a flux detecting area α and the magnet 51 can be shortened. By shortening the distance x, precision of detection can be improved, and also the magnetic flux intensity of the magnet 51 is not necessary so strong, therefore an inexpensive ferrite based plastic magnet can be used. Furthermore the cost can be reduced because the fluctuation of magnetic flux detecting means 52 etc., are protected by covering with an inexpensive protecting layer 55 protecting from the dew condensation or the oil instead of the expensive potting 16.

摘要： PROBLEM TO BE SOLVED: To provide an opening/closing valve reducing a fluid leakage amount without enlarging a size. SOLUTION: In a worm gear 21 and a helical tooth 30b of a gear 30, drive force is transmitted from a motor 20 to the gear 30, but a meshing angle is formed without transmitting drive force from the gear 30 to the DC motor 20. A spring 34 is interposed in a drive force transmitting route from the gear 30 to a shaft 32. Even after a valve member is seated in a valve seat, the DC motor 20 is further rotated in a valve closing direction, the spring 34 is wound up, by elastically deforming the spring 34, its energizing force acts in a direction pressing the valve member including a spool 37 to the valve seat. Accordingly, when an opening/closing valve is closed, leaking of vaporized fuel from a contact part between the valve member and the valve seat can be suppressed. Even when the energizing force of the spring 34 acts in a valve opening direction of the gear 30, by locking meshing of the worm gear 21 and the gear 30, even when carrying of a current in the DC motor 20 is turned off, the opening/closing valve is surely closed.

摘要： PROBLEM TO BE SOLVED: To reduce impact noise which is generated when a movable iron core is attracted (at the time of valve opening). SOLUTION: A movable iron core 7 which is disposed facing a stationary iron core 5 in the inner circumference of a bobbin 3 is secured at a leaf spring 9 of its flange part 71 and is attracted to the stationary iron core 5 side when the coil is energized. A valve element 8 which is fixed at the leaf spring 9 with the movable iron core 7 is energized to a valve seat 12 side by a spring 18 disposed between a piece 6 positioned at the stationary iron core 5 and the leaf spring 9. While the coil is not energized, the valve element 8 receives energizing force of the spring 18 and touch the valve seat 12, thus shutting-down being generated between an inflow passage 10 and an outflow passage 11. The valve element 8 leaves the valve seat 12 and opens the inflow passage 10 as a result of the leaf spring 9 being deflected against the energizing force of the spring 18 when the coil is energized and the movable iron core 7 is attracted to the stationary iron core 5 side. At this time, the valve opening position of the valve element 8 is regulated by bringing the end surface 8b of the piece of the valve element 8 into contact with the stopper surface 6a of the piece 6.

摘要： PROBLEM TO BE SOLVED: To prevent contact fault between each motor terminal and a terminal due to vibration. SOLUTION: Terminals 28 and a holding plate 27, having holding holes for holding a bearing supporting unit 32 projecting toward the lower end side of a motor 22 are incorporated through insert molding of resin to form a terminal assembly 26. At the same time with press-fitting the bearing supporting unit 32 of the motor 22 into the holding hole of the holding plate 27, the terminals 36 of the motor are press-fitted into the connecting holes of the terminals 28. After this, the lower end side (bearing supporting unit 32 side) of the motor 22 is fixed to a housing 23 via the terminal assembly 26, by fixing the terminal assembly 26 to the housing 23. Thereafter, a fitting board 41 fitted to the upper end side of the motor 22 is fixed to sidewalls 38, 39 of the housing 23 with screws 46. Consequently, the motor 22 is fixed both on the upper end side and on the lower end side.
