Abstract

A lever device is configured such that, when first and second plates are relatively moved in a direction in which a second end part of the first plate and a fourth end part of the second plate are close to each other from a state in which the second end part and the fourth end part are separated from each other in an axial direction of a bolt, the first plate is rotated around a fulcrum positioned between a first engagement part and the second end part in the crossing direction so that the first plate is moved from an engaged position where the first engagement part and a non-circular part of the bolt or a nut are engaged to a non-engaged position where they are not engaged, and thereby removing a restriction of the relative rotation of the first plate to the non-circular part.
