<p><P>PROBLEM TO BE SOLVED: To provide a pointer mounting structure of a rotating shaft in which illumination light is efficiently propagated down to a pointer without largely deteriorating the light emission efficiency of the pointer, and which can prevent the generation of a crack. <P>SOLUTION: The vertex of a press-fitting part 81 which is deformed in such a shape that follows the inner surface of a press-fitting hole 93 when the press-fitting part 81 is press-fitted into the press-fitting hole 93 contacts with the inner surface of the press-fitting hole 93. Based on the length of a crossing line where a surface at which the outer surface of the press-fitting part 81 contacts with the inner surface of the press-fitting hole 93 crosses a cross section orthogonal to the press-fitting part 81 in radial direction, a press-fitting force when the press-fitting part 81 is inserted into the press-fitting hole 93 or a pull-out force when the press-fitting part 81 is pulled out of the press-fitting hole 93 is set. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
