Magnetic disk device and guide member for guiding a flexible wiring board

A disk device, comprising:

• a carriage which is rotatably supported, and has an assembly comprising a magnetic head disposed at a front side and a coil disposed at a rear side;
• a strip-shaped flexible wiring board which has one end attached to a side portion of said carriage and is electrically connected to said magnetic head and said coil;
• a guide member for guiding said flexible wiring board which extends from a rear side to a side portion of said carriage in such a way that an other end of said flexible wiring board is oriented toward a mounting position;
• two projecting components comprising a front-side projecting component and a rear-side projecting component which are arranged to a front and a rear portion of said carriage respectively and are provided on a side portion of said carriage;
• and
• said guide member comprises:
• a U-shaped component which comprises a pair of edge components and is formed into a U-shape, wherein said U-shaped component is inserted between said two projecting components and said pair of edge components come into contact with said two projecting components, respectively, wherein said U-shaped component is elastically deformed in such a way that said pair of edge components come closer together;
• and
• an arm component which comes into contact with said flexible wiring board from a rear side and is narrower in width than said flexible wiring board.
