This pointer-type meter is provided with a display board and a pointer that is connected to a driving device and rotates on the display board. The display board has two types of indicator parts that express vehicle speed in different units of km / h and MPH. They are arranged concentrically, and these two types of indicator parts are indicated by a single pointer, but the pointers radiate from the common array center of the two types of indicator parts toward a predetermined value of each indicator part. In addition to being arranged so as to extend, the indicator part arranged in the inner side (in this case, the scale part indicating km / h and the numerical part) is the indicator part arranged in the outer side (in this case, the scale part showing MPH) Therefore, there is room for improvement in terms of readability because the indicator portion arranged on the inside is covered by the pointer.

  On the other hand, for example, as described in Patent Document 2 below, the display plate is provided with a slit that allows the pointer to turn, and the measured value is obtained using the pointer that passes through the back of the display plate and is exposed to the front of the display plate through the slit. A pointer-type instrument is also known, and if an indicator part of a unit different from the indicator part arranged outside is arranged inside the slit, the indicator passes through the back surface of the display board, so that one pointer Since different types of index parts can be indicated without covering all (at a predetermined value) of one index part, the readability can be improved.
