Abstract: A pump housing, a fixing member and a holding member are assembled in the axis direction of an oil pump to fix a stator and a rotor of a brushless motor. The holding member is made of metal material and has a cylindrical shape that extends from its bottom portion toward one side in the axial direction. The fixing member is a cylindrical metal member. Stepped portions, extending in the circumferential direction, are formed in the outer periphery of the holding member and the inner periphery of the fixing member, and contact each other. The outer periphery of the holding member engages with the inner periphery of the fixing member. The outer periphery of the other end portion of the fixing member is fitted to the inner periphery of a flange portion projecting from the end face of the pump housing, which is adjacent to the brushless motor.

Abstract: A radial magnetizing part including permanent magnets is disposed so as to face a rotor unit in a radial direction of the rotor unit. Axial magnetizing parts are disposed on both end faces in an axial direction of the rotor unit. The axial magnetizing parts include low magnetic permeability portions and high magnetic permeability portions. The low magnetic permeability portions are disposed so as to face magnet materials. Magnetic flux from the N pole of the permanent magnet of the radial magnetizing part enters a core in the radial direction, crosses the magnet material, and returns to the S pole of the permanent magnet. The magnetic flux from the N pole of the permanent magnet of the radial magnetizing part also enters the core through the high magnetic permeability portions of the axial magnetizing parts, crosses the magnet material, and returns to the S pole of the permanent magnet.

Abstract: A steering device includes a movable body that rotatably supports a shaft member to which a steering member is attached, and first and second rail mechanisms that guide movement of the movable body in a front-rear direction. The first rail mechanism has a first rolling element row that is disposed between a first raceway face of a first fixed rail and a second raceway face of a first moving rail. The second rail mechanism has a second rolling element row that is between a third raceway face of a second fixed rail and a fourth raceway face of a second moving rail. A contact angle of each of a plurality of first rolling elements with respect to the first and second raceway faces, and the contact angle of each of a plurality of second rolling elements with respect to the third and fourth raceway faces are different from each other.

Abstract: An interior permanent magnet rotor restrains demagnetization of permanent magnets embedded in a core. Each permanent magnet is formed by joining a first portion and a second portion at a connection. The first and second portions extend from the outer side toward the inner side in the radial direction of the core. The outer end faces of the first and second portions in the radial direction of the core extend in an orientation direction as viewed in section perpendicular to the axial direction. The outside diameter of the core gradually increases from the boundaries between a single magnetic pole and magnetic poles adjoining the single magnetic pole toward the middle of the single magnetic pole in the circumferential direction of the core.

Abstract: In an internal gear pump that includes an inner gear having outer teeth and an outer gear having inner teeth, either the inner or outer teeth have a shape based on a tooth shape that is respectively formed by a generating curve of the outer or inner teeth. The inner teeth are arc-shaped, the outer teeth are curved-shaped, and both end sections of the curved shape are arc-shaped. If a radius of the arc shape of the inner teeth is set as ro, a radius of the arc shape of each of the corner sections is set as ri, a diameter of a pitch circle of the inner teeth is set as dp, and the number of the inner teeth is set as z, the inner gear and the outer gear each has a shape that satisfies a relationship established by following equations: 1.6>ro/(dp/z)>1.0; and ro/(dp/z)>ri/(dp/z)≧0.13. Each of the inner teeth is provided so that an intersecting point between one of arcs that follow the first arc shapes of the adjacent inner teeth and the pitch circle of the inner teeth and in proximity to the other arc is located outside of the other arc.
