Claims

[Scope of utility model registration request]

In a rotary stopper that is pivoted on the base side via a shaft and reciprocated from an upright state to one side about the shaft by a driving means, the stopper is connected to the stopper via a hinge pin coaxial with the shaft. A pivotably connected connecting arm and a contact portion for regulating the range of reciprocating rotation of the connecting arm are provided, a drive means is connected to an end of the connecting arm, and a stopper is provided between the connecting arm and the base side. 1. A locking device for a rotary stopper, characterized in that an engaging portion is provided for suppressing rotation of the stopper, which engages and disengages each other by reciprocating rotation of the connecting arm when the connecting arm is raised.
