Claims

[Scope of utility model registration request]

A locking recess is provided on the periphery of one of a pair of rotary disks that are mutually rotatably supported, and the other rotary disk is capable of being fitted into and removed from the locking recess in the fitting direction. In a joint device including a biased locking piece and a locking release lever that moves the locking piece in a release direction, the other rotary disk is retracted to a release position by the locking release lever. An automatic engagement stopper is provided that enters between the tip of the moved locking piece and the periphery of the one rotary disk to hold the locking piece in the disengaged position, and the two rotary disks are moved relative to each other in the forward direction. When rotating, an engagement release operation part is formed on the periphery of the one rotary disk to move an automatic engagement stopper that holds the engagement piece in the disengagement position to a disengagement position in front of the engagement recess. A joint device with locking means consisting of:
