Claims

[Scope of Claim for Utility Model Registration] 1. In a cylindrical joint receiver that is fixed to a small diameter hole on the tip side of a stepped hole of a head in order to removably fix the joint body at the tip of the shaft to the head, a stepped hole. A male thread is provided on the outer circumferential surface on the proximal side from the position corresponding to the stepped portion of the joint receiver that is fixed to the joint receiver, and a protrusion-shaped crest on the outer circumferential surface on the distal side from the male screw portion bites into the inner circumferential wall of the small diameter hole. A joint receiver for a ball game stake, characterized in that a spline with a diameter is provided, and a retaining plate is installed in the diametrical direction along the axial direction on the inner peripheral surface of the tip side. 2. A joint receiver for a ball game stake according to claim 1, wherein each crest of said spline is provided with one or more notches. 3. Claim 1 or 2, wherein the outer circumferential surface on the distal end side of the joint receiver is provided with a smooth introduction part that has approximately the same diameter as the trough of the spline and can be inserted coaxially into the small diameter hole.
Joint receiver for the listed ball game stake.
