It is preferable to include a seal holder attached to the support for supporting the seal, and a bolt for fixing the seal holder.

The configuration of the present invention is preferably such that the above-mentioned O-ring is mounted in the O-ring groove of the conveying body.

In the constitution of the present invention, it is preferable that the above-mentioned seal is formed in the shape of a donut in the hole.

The configuration of the present invention is preferably such that the seal is formed smaller than the radius of the inner circumferential surface of the O-ring so that the seal can support the O-ring.

The configuration of the present invention is preferably such that the seal has the same properties as the slide bearing.

The configuration of the present invention is preferably such that the seal holder is mounted in the seal holder groove of the conveying body.

In the configuration of the present invention, the seal holder is preferably in the form of a donut in a hole formed therein.
