摘要： The present invention aims to improve the efficiency of a clamping step for combining a flange with a shaft and to improve productivity. The shaft and the flange are previously tentatively combined in the tentative clamping step. In the tentative clamping step, a concave part at the end of the shaft is pressurized by a metal mold such as a ball to be enlarged to an outer circumferential direction, and then, pressurizing this concave part against the inner circumference of the flange, the concave part is fixed. The combined body made by tentatively combining the shaft and the flange is strongly combined in a proper clamping step. In order to correct a distortion such as a warpage of the flange that has been solidly combined by the proper clamping step, sandwiching the flange by the upper and lower metals, the flange is pressurized and a flash molding is carried out.

摘要： This invention pertains to a rotor core (6) in which a plurality of core sheets (1) are laminated on one another on a rotor shaft (4). A plurality of slits (3, 7) and a plurality of strips (2) are alternately arranged in a radial direction of each of the core sheets (1) so as to convexly confront a center of each of the core sheets (1) such that an outer peripheral rim (10) is formed between an outer peripheral edge of each of the core sheets (1) and each of opposite ends of each of the slits (3, 7). A stress concentration portion (11) which is provided at a portion (10a) of the outer peripheral rim (10) and has a width (L1) larger than that of the remaining portions of the outer peripheral rim (10).

摘要： The cross sectional shape of an axial direction communicating path when viewed in the axial direction is flat in the circumferential direction, and the cross sectional area of the communicating path gradually decreases moving from the center of the cross section toward the both ends in the circumferential direction. When a sleeve and a cover member are bonded with an adhesive, the adhesive is actively made to flow into an adhesive inflow portion.

摘要： The present invention provides a small and thin spindle motor in which no uneven pressure is applied to a recording medium when the recording medium is fixed to a hub, a disc driving apparatus having the spindle motor, and a production method thereof. The spindle motor comprises: a sleeve which is supported by a fixed shaft and rotates around a predetermined axis; and a hub provided on an outer peripheral portion of the sleeve, which includes: a tubular portion to be inserted into a central hole of a recording medium having a disc shape, which is coaxial with the sleeve and has a male thread formed on an outer peripheral surface; and a first receiving surface which is connected to the tubular portion and which holds the recording medium to the axis.
