Claims

[Claims for Utility Model Registration] (1) A cylindrical connecting shaft with at least one end open, which has a protrusion on the inner surface of the cylinder that gradually increases in height from the open side to the deep part, and has a rod-like shape. By fitting the end of the transmission shaft into the cylindrical connection shaft and engaging the projection formed at the end of the transmission shaft with the engagement groove formed between the protrusions, the transmission In a cylindrical connecting shaft configured to transmit rotational force around the axis between the shaft and the shaft, the ridge of the protrusion has a raised center and an engagement groove on both sides of the protrusion. A cylindrical connecting shaft characterized in that two inclined surfaces are formed that meet each other. (2) A cylindrical connecting shaft with at least one end open, which has a protrusion on the inner surface of the cylinder whose height gradually increases from the opening side to the deeper part, and the end of the rod-shaped transmission shaft is connected to the shaft. By fitting into the cylindrical connecting shaft and engaging the protrusion formed at the end of the transmission shaft with the engagement groove formed between the protrusions, the shaft rotation between the transmission shaft and the transmission shaft is achieved. In the cylindrical connecting shaft configured to transmit rotational force, an end of the protrusion on the opening side is sharpened, and an inclined surface extending from the end to the engagement groove is formed on the side surface of the protrusion. A cylindrical connecting shaft characterized by being formed in a part of the opening side.
