Abstract
A mechanical stopper device wherein a fixed body includes a fixing-side stopper, including: a lever that can swing about a supporting shaft provided to the fixed body; and a pair of elastic bodies, attached to the fixed body, on both sides in the lever swinging direction, and which can contact with both side surfaces of the lever. Further, a rotating body includes a stopper pin that can be in contact with both the side surfaces of the lever. The ratio between a distance (a) from a supporting point of the lever to a contact position where the lever and the stopper pin are in contact with each other, and a distance (b) from the supporting point of the lever to a contact position where the lever and the elastic bodies are in contact with each other is 1.05≤a/b≤2.30, and thickness (D) of the elastic bodies is 20 mm≤D≤40 mm.
