(Means for Solving the Problem) Therefore, the L-shaped pipe striped arm according to the present invention has a governor arm main body and a rotatable pipe joint main body. It consists of a fitted rotating part and a connecting end following the rotating part to which a hose etc. is connected,
It is an L-shaped pipe line that changes the direction of fluid flow. With a structure characterized in that a fitting part between the pipe joint body and the rotating part has a packing, and a plurality of rolling balls are inserted into raceway grooves of eaves balls provided in the fitting part, This aims to achieve the above objectives. (Function) With the above configuration, the rotating part is connected to the pipe fitting main body by the plurality of rolling balls inserted into the raceway groove of the fitting part between the pipe fitting main body and the rotating part, and also rotates lightly. be able to. Further, the packing of the fitting portion prevents fluid from leaking from the fitting portion. When a force in the rotating direction is applied to the connected hose, etc., the rotating part rotates to prevent the L-shaped pipe repair handle from loosening and to prevent excessive force from being applied to the hose, etc.

Fig. 1 is a partial sectional view of the L-shaped pipe joint A, and Fig. 2 is an enlarged side view of the same main part. la is a pipe joint body with a through hole, 2a is a pipe joint body 1
The rotating part 3a is rotatably fitted into the rotating part 2a.
The connecting end is screwed into the rotating part 2a, forming an L-shaped tube together with the rotating part 2a. Then, a raceway groove 6 is formed on the same circumference of the fitted portion of the inner circumferential surface of the pipe joint body 1a and the outer circumferential surface of the rotating portion 2a, and in which the rolling ball 5 rolls. are doing. A plurality of rolling balls 5 are inserted through the rolling ball insertion hole 7 which communicates from the outer circumference of the fiber hand main body 1a to the raceway groove 6 of the rolling ball 5, and are arranged in a full orbit. Note that the rolling ball insertion hole 7 is closed with a blind plug screw 8 after the rolling ball 5 is inserted.
