特徴とするピン装置。 one bracket member having a pin insertion hole;
In a pin joint part which rotatably connects a boss member serving as a counterpart member to each other by a connecting pin and has a locking part for preventing the pin from coming off on the outer side of the bracket, a collar part is provided on the pin head, and on the other hand, Forms a collar whose inner diameter is slightly larger than the outer diameter of the brim,
and a stepped portion with an inner diameter larger than the inner diameter is bored on the inner peripheral surface of the collar, and the small inner diameter side surface of the collar is fixed to the outer side of the pin hole of the bracket member as the outer side, When inserting the pin, a locking member for preventing the pin from coming off is removably attached to the stepped portion of the inner diameter of the collar at a position on the outer side of the collar of the pin, and the pin is rotatable and axial within the pin insertion hole. A pin device characterized in that it is configured to be immovable in the cardiac direction.
