Abstract

PURPOSE:To simplify the operation while allowing the eased working accuracy of parts by positioning a fixed slit plate in contact with a jig inserted into a rotating shaft. CONSTITUTION:A jig 12 having a key section 11 is inserted into a rotating shaft 5 pivoted on a body 1 and a fixed slit plate 3 is brought into contact with the key section 11 to position. An adhesive is applied on the surface of the body 1 to fasten the fixed slit plate so that the fixed slit plate will be fastened as positioned. The jig 12 is pulled out and a rotary slit plate is mounted in stead. This simplifies the operation while allowing eased working accuracy of parts.
