PURPOSE:To easily set a blade and to simplify assembly and adjustment by providing a part which is bent at an obtuse angle at a contact part and linearly extended toward a free end from the bent part on the surface of the blade opposed to a carrier. CONSTITUTION:This blade 10 is constituted of a metallic plate such as a stainless plate, a synthetic resin plate, rubber or a member obtained by properly coating the surface of each plate. The opposed surface to a sleeve on the tip side of the blade 10 is linearly cut so that its thickness may get smaller and smaller toward the tip part 101 from a beginning part 102 positioned at a specified distance S away from the tip part 101. An acute angle being an angle(180 deg.-theta) is formed at the beginning part(bent part) 102 by a linearly inclined surface 103 cut and formed in such a way and a surface 104 on a fixed side, and the bent part 102 or its vicinity is allowed to press-contact with a sleeve 7. In the case of cutting the blade 10, it is desirable to work the blade 10 so that the fine ruggedness can not be formed on the inclined surface 103. |
