In addition, when replacing the annular lamps 22 and 23, the removal operation parts 35 on both sides of the lamp holding part 21 are pressed from the operation recesses 15 to deform the locking pieces 34 inward. The lamp holder 21 can be disengaged from the locking hole 6 and removed from the fitting recess 5 of the first body 1 of the instrument. In this way, the annular lamps 22 and 23 are attached to the lamp holder 21, and the lamp holder 21 is attached to the lamp holder 21.
can be separated from body 1.

The lamp holder 21 is then moved to a position where the annular lamp 22.23 can be easily replaced, thereby facilitating the replacement of the annular lamp 22.23. When holding the lamp holder 21, the lamp holder 22, which has a large tube part, is located on the lower side and has good stability, allowing the lamp holder 21 to be placed stably and making it easy to replace the annular lamps 22 and 23.
