The extension unit is extended to the lower side in the outer boundary of the main body. The flange is extended to the columnar direction in lower part of the extension unit. The flange blocks the lower part of the dust cover. The dust cover has a barrier groove in lower part. In lower part of the extension part, a protrusion(25), which is inserted to a barrier groove, is formed. |
