せて設けられる。(Prior Art) Conventionally, the flip of a Western umbrella is integrally formed of a metal material and is installed inside the center rod. It is provided so that it can freely move in and out through a slit formed in the center rod, and is always biased by elasticity so as to protrude outward.

除操作するための押圧時において指先に強く当る
等の問題があつた。 By the way, in order to form a repellent from a metal material, the metal plate is first punched out by press working, then polished to remove burrs, and then plated, which has the drawback of requiring a lot of processing time. Furthermore, the elasticity of the metal material is hard, and there is a problem in that the metal material hits the fingertip strongly when pressing to release the locking portion.

し得るようにしたものである。(Problems to be Solved by the Invention) The present invention has been made by focusing on the above-mentioned points, and allows the repellent to be easily manufactured from a synthetic resin material, and also to obtain a sufficient locking effect on the potter's wheel. This allows the release operation to be carried out easily while maintaining the necessary elasticity.

At the same time, a locking protrusion for the locking hole of the center rod is provided at the base, and an elastic piece is branched from the main rod portion to abut the center rod and urge the locking piece outward together with the main rod portion. We adopted a configuration in which

When the umbrella is in use, as shown in FIG. 1, the locking piece 3 protrudes from the slit 7 of the small diameter pipe _B1 , and the engaging stepped portion 3a engages with the edge of the slit 7 to prevent sliding. Support potter's wheel C.

いる。 When closing the umbrella, press the locking piece 3 to close the end 5.
While sliding the elastic piece 5 and stretching the curved main rod part 1, the locking piece 3 is attached to the small diameter pipe.
It is inserted into B ₁ , and in this state, as shown in Figure 2, it slides in the direction of polymerizing the large diameter pipe B ₂ to reduce the size of the rod B during expansion and contraction. Since it is rich in lubricity and has flexible elasticity, the expansion and contraction operations of the center rod are extremely easy. As shown in FIG. 3, the elastic piece 5 is formed wide so that it can maintain sliding contact with the main rod part 1.
