    摘要： Using a simple and inexpensive method, a reliable spindle motor having a simple and inexpensive structure is afforded, in which contact failure of the FPC does not occur even when the motor undergoes external impact. An extending portion is provided radially outer side of an annular recess of a base. The extending portion has a step whose radially outer side is higher, and a through hole formed such as to pass through the base from its inside to outside. A FPC is disposed on an upper surface of a stator. The FPC is fixed to a lower surface of the base through the through hole. The bending height and the bending angle of the FPC are minimized by providing the step having appropriate height so that the FPC is not easily peeled off even when subject to external impact.

    摘要： A plate-like material is pressed and a middle concave portion centered on a center axis is formed in one axial surface of the material. Likely, an annular concave portion centered on a center axis and radially outwardly arranged is formed in one and/or the other axial surface of the material. The material is then cut along a radially outer rim of the middle concave portion, and between a radially outer rim and a radially inner rim of the annular concave portion. In this way, a thrust plate having indented portions at radially inside and outside portion of the one and/or the other axial surface thereof is manufactured. A burr formed in press working is accommodate within the indented portion and does not axially protrude from the one and/or the other axial surface of the thrust plate.

    摘要： A sleeve has a thrust dynamic pressure generating groove arrangement for generating a dynamic pressure in a thrust direction between another member and the sleeve. The sleeve is formed in the following manner. First, a mold is prepared which is provided with a portion corresponding to the thrust dynamic pressure generating groove arrangement. Injection molding is carried out by using this mold and material containing binders and metal particulates, thereby forming a work-in-process piece having the thrust dynamic pressure groove arrangement in a cavity of the mold. Then, binders in the work-in-process piece are removed by heating, and thereafter metal particulates in the work-in-process piece are sintered.

    摘要： A motor includes a stationary portion and a rotating portion. The rotating portion includes a sleeve portion. The sleeve portion includes a communicating hole. A dynamic pressure bearing is defined in a first gap between a shaft portion and the sleeve portion. An upper seal portion and a lower seal portion are arranged radially outward of the dynamic pressure bearing. The upper seal portion and the lower seal portion are arranged in communication with each other through the communicating hole. The communicating hole and a space extending from the upper seal portion to the lower seal portion through the first gap are filled with a lubricating oil. A fixing region where an outer tubular portion and a base portion are fixed to each other is arranged to overlap with the dynamic pressure bearing in a radial direction in plan view.

    摘要： A bearing apparatus includes a stationary shaft, a first annular member, and a rotating member. The rotating member includes a first inner circumferential surface arranged opposite to the outer circumferential surface of the stationary shaft, and a second inner circumferential surface arranged opposite to an outer circumferential surface of the first annular member. A lubricating oil is arranged in a gap between a surface of a stationary member and the rotating member. On an upper side of an upper surface of the lubricating oil, the first annular member and the rotating member are arranged radially opposite to each other with a slight gap defined therebetween, so that a labyrinth seal is defined. The labyrinth seal and a fixing range over which the stationary shaft and the first annular member are fixed to each other are arranged to overlap with each other in a radial direction.
