2. Description of the Related Art For example, as one of the modes for recording sound in a music
hall or a theater, a microphone may be used by being suspended from a ceiling or the like
through its cord. In that case, in a microphone with strong directivity, it is necessary to angle the
microphone toward the sound collection point. A cord suspension type microphone holder used
for this is described in the prior art with reference to FIG.
[0003]
In this example, what is suspended is a so-called gun-type microphone M, and in order to make
this microphone M have a predetermined angle in the air, conventionally, a wire coated with
resin such as polyvinyl chloride is coiled (helical step shape The microphone holder 1 wound
around is used.

of the microphone M is inserted, and a cord insertion portion 3 into which the cord C of the
microphone M is inserted, and a non-coil bending portion 4 is formed between them. ing.
According to this, it is possible to turn the microphone M in a desired direction by bending the
wire of the bending portion 4.
[0005]
However, the first thing that can be said is that the cost of the resin coating (for example,
polyvinyl chloride coating) on the wire and its helical processing is high, which is not preferable
in cost.

Second, in order to insert the cord C of the microphone M into the cord insertion portion 3, the
cord C has to be inserted from between the spirals of the cord insertion portion 3, which takes
time and is difficult to handle.
[0007]
In addition, small parts of this type are often packaged in a plastic bag (polyethylene bag), but
since the surface is resin-coated, the resin coating often adheres to the plastic bag and the
packing operation is There were issues such as being difficult to do.
