1. A center-less pointer type display apparatus comprising:
a pointer moving device that includes a pointer section which supports a pointer and a carrying section which carries the pointer section and is formed in a substantially semicircular arc or substantially ellipse shape; and a containing case that is formed of a case body which is covered by a semicircular shaped dial plate having an opening portion near its center, the containing case accommodating the pointer moving device so that the pointer indicates a scale on the dial plate, wherein the carrying section has a guide rail having a transverse U-shape in cross section and a wire which is moved along the guide rail; wherein the pointer section has a first support member which supports an upper pulley and a second support member which supports a lower pulley, a spring is interposed between the first support member and the second support member so that a lower portion of the spring pushes the first support member and an upper portion of the spring pushes the second support member, and thereby the upper pulley on the first support member and the lower pulley on the second support member hold an upper portion and a lower portion of the guide rail, respectively; and wherein a wire fixing section adapted to fix the wire is provided at an intermediate portion of the pointer section on a line connecting the upper pulley and the lower pulley, and the wire is fixed to the wire fixing section. |
