Abstract
To prevent an erroneous installation of a rotational detection lever and a rotational element, one of a plurality of toothed portions of a rotational element is made into a larger toothed portion which is larger in pitch and/or tooth height, and one of a plurality of tooth grooves of a rotation detection lever is made into a larger tooth groove which can mesh with the larger toothed portion when the rotational element and the rotation detection lever are positioned so as to correspond to each other.
