of the base side portion 9, and the base side microphone unit 5-1 is The flat plate material having
a spring property is curved in an arc shape, and the lower microphone holding members 5A and
5B are provided, and the upper and lower microphone holding members 5A and 5B hold the
plurality of microphones 74, The upper and lower microphone holding members 5A and 5B are
inserted into the base portion 9 in a state where they are pressed, and the microphone 74 is
exposed to the window for exposing the microphones 17 and 17-1. By holding the microphone
04-05-2019
18
74 by pressing the upper and lower microphone holding members 5A and 5B against the inner
surface of the base side portion 9 by force, the microphone 74 is attached to the base 1 without
using a screw member. Can reduce the number of parts It can be current.
[0069]
Further, according to the embodiment of the present invention described above, one pole-side
portion 12 is provided with one insertion groove portion 25 and the other pole-side portion 12 is
