发明名称 BASE UNIT, SPINDLE MOTOR, AND DISK DRIVING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a structure which fixes a connector to an upper surface of a base member of a disk driving device with an adhesive, interrupts communication through a window part, and inhibits protrusion of the adhesive.SOLUTION: A window part 70A penetrates through a bottom plate part 211A of a base member in an axial direction. A first groove 71A is provided on an upper surface of the bottom plate part around the window part. Further, the connector 62A includes a substrate part 621A and an electrode terminal 622A provided on a lower surface of the substrate part. The substrate part is disposed on the upper surface of the bottom plate part and covers the window part and the first groove. An adhesive 41A is disposed between the upper surface of the bottom plate part and the lower surface of the substrate part thereby fixing the bottom plate part to the substrate part. Further, the adhesive annularly connects around the window part. This adhesive structure interrupts the communication through the window part. When a connector is adhered to the base member, a part of the adhesive before hardening is retained in the first groove.
