Claim 2:
3. The optical adapter holding structure according to claim 1, wherein
hard magnetic bodies are fixed on each side of the direction in which the optical adapters are provided side by side, or on each side of a direction in which the insertion holes of the attachment tool are provided side by side;
a part of the attachment tool facing the hard magnetic bodies provided on the optical adapter, or a part of the optical adapters facing the hard magnetic bodies provided on the attachment tool, is formed of another hard magnetic body or a soft magnetic body that can be attracted to the hard magnetic bodies;
an attractive force of the hard magnetic bodies can hold the optical adapters in the direction substantially vertical to the attachment tool when each of the optical adapters is inserted into the insertion hole, and when each of the optical adapters receives a force greater than the attractive force of the hard magnetic bodies, one of the hard magnetic bodies separates away from a facing face so that each of the optical adapters can sway.
