[Takahashi, Okutomi, Shoda]

We tightened the screws of the inner frame.

Also, we tried to test the wind shield of the Oplev.
But we found that the noise of the Oplev was larger than usual even without the wind shields.
The noise level did not get better though we adjust the Oplev laser so that it is not clipped on RM. We could not find any other clipping points.
Note that we do not have enough access on the Oplev side this time since the flange on the PRM side is closed by the duct.

Anyway, we released the suspension from the security frame to check the noise level again.
Then, it recovered.

Therefore, we will try to see the wind shield effect with suspension released later.
