A lens-holding shaft 41 displaces a lens 1 towards a main rotating tool 50 for processing the peripheral portion of the lens 1. A long hole 115 penetrating a waterproof case 101 is formed in the waterproof case 101 along the locus of displacement of the lens-holding shaft 41 and the lens-holding shaft is inserted through the long hole 115. At the outside of the waterproof case 101 along the long hole 115, a flexible water-resistant sliding shutter 130 is disposed in a manner such that the sliding shutter 130 can be freely displaced. The sliding shutter 130 is connected with the lens-holding shaft 41. A guide member 150 containing the sliding shutter 130 is bent at a position before the main shaft 51.
