  A dial plate 3 '' shown in FIG. 10 is provided on a sixth curved line portion R6 constituted by the scale and the numbers arranged on a curved line, and on an extension of the sixth curved line portion R6. And the 3rd straight line part S3 comprised by the said scale and said number arranged on the straight line, the curve provided on the extension of this 3rd straight line part S3, and the direction opposite to 6th curved line part R6 A display portion 3a '' having a seventh curved portion R7 constituted by the scale and the numbers arranged above, and an opening 3b '' provided along the display portion 3a '' And are provided.

  According to the present embodiment, it is possible to give a degree of freedom to the arrangement direction of the display units 3a, that is, the arrangement direction of the scales, and even if the display unit 3a is formed in an S shape or a wavy shape, The speedometer 1 having the moving mechanism 2 that can move the pointer 41 along the display unit 3a, is space-saving, and can operate the pointer 41 smoothly and accurately can be provided. Further, since the moving mechanism 2 has a space-saving configuration, the degree of freedom of layout and the degree of design of the speedometer 1 can be improved. Furthermore, the speed at which the pulley assembly 6 can be shared by the dial plates 3, 3 ′, 3 ″ having different arrangement directions of the display units 3 a, 3 a ′, 3 a ″, that is, the scale arrangement directions. A meter 1 can be provided.

  In the above-described embodiment, the pulley assembly 6 having the plurality of pulleys 61 and 52 is used as the “guide member”. However, in the present invention, the “guide member” does not necessarily include the pulleys 61 and 52. For example, a hook-like member formed in a shape along the arrangement direction of the display units 3a can be used as the “guide member”. In other words, the “guide member” of the present invention may be any member as long as the curved surface along which the flexible member 5 is provided is provided at least partially, and the moving direction of the flexible member 5 can be defined.

  In the above-described embodiment, the speedometer 1 mounted on the vehicle has been described as an example of the instrument device. However, the present invention is not limited to the instrument device for the vehicle, and the instrument device is used in other fields. Can also be applied.

  In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.
