  However, the pointer-type meter described in Patent Document 1 is provided with a ring-shaped shielding member in front of the outer peripheral portion of the display plate so that a bypass portion that bypasses the side of the display plate and reaches the display plate is invisible. Therefore, it is easily recognized that the pointer indicating portion is supported at a location where the shielding member becomes invisible, particularly when viewed from the lateral direction. Then, there is a concern that a user who is accustomed to normal pointer-type display that instructs the display unit from the inside of the display board (display unit) may feel uncomfortable.

  Therefore, the present invention pays attention to the above-described problems, and an object thereof is to provide a pointer-type instrument that can reduce a sense of incongruity while adopting a configuration in which a display unit is designated from the outside of a display board.

The present invention relates to a pointer, a display member that displays various types of information in accordance with an electrical signal, a window portion that is disposed in front of the display member so that the display member can be visually recognized, and a display that is disposed around the window portion. A pointer-type meter configured to indicate the display unit from the outside of the display plate, wherein the window portion corresponds to a rotation trajectory of a tip portion of the pointer. And an edge member that borders the window, and the pointer overlaps the edge member in the thickness direction of the display member.
Since the pointer and the rimming member overlap in this manner, the pointer and the rimming member look as if they are an integral part. From this, it is possible to make an illusion that the display unit is instructed, thereby reducing a sense of incongruity.

Further, the present invention includes an indication portion in which the pointer extends from the outside of the display plate toward the window portion, and a cover that is formed in the same color or a similar color as the rim member and covers a required portion of the indication portion. The cover overlaps the edging member in the thickness direction.
In this way, when the pointer has a cover, the illusion that it seems to indicate the display unit from the inside of the display board is strengthened by overlapping the cover with the same color or similar color as the edge member, thereby making it uncomfortable. Can be further reduced.

In the invention, it is preferable that the cover has an extension portion facing an inner peripheral portion of the edging member and a rotation plane direction of the pointer.
Since the cover has the extension portion in this manner, the pointer can be seen as if it is coming out from behind the display board facing the window, and thus it seems to indicate the display section from the inside of the display board. The illusion can be strengthened and the uncomfortable feeling can be further reduced.
