It is formed of a pipe material having a non-circular cross section, in the case of the illustrated example, a pipe material in which grooves 38 are provided at portions facing each other in the circumferential direction. On the other hand, the second pipe material 31b is formed of a pipe material having a circular cross section (annular shape) into which the first pipe 31a is slidably inserted, but the second pipe material 31b has the same cross-sectional outer shape as the first pipe 31a at the tip. A sleep 39 having an internal cross section is fixed by caulking 40 or the like, and the first pipe 31a is slidably inserted through the sleeve 39. Therefore, the first pipe 31a has a stopper 41 fixed to the groove 38 in the vicinity of the tail end, and when the first pipe 31a is extended from the second pipe 31b, the stopper 41 comes into contact with the sleep 39 to remove the first pipe 31a. It constitutes a stopping means. Furthermore, at the tail end of the first pipe 31a,
The ball 43 elastically held by the spring 42 is configured to project from the outer peripheral surface, and when the first pipe 31a is extended from the second pipe 31b, the ball 43 enters and locks in the hole 44 of the second pipe 31b. By doing so, a temporary fixing means for temporarily fixing the first pipe 31a to the second pipe 31b so as not to contract freely is configured. Therefore,
When the first pipe 31a is extended from the second pipe 31b, the first pipe 31a and the second pipe 31b cannot rotate about their axes, and the stopper 41 prevents the first pipe 31a from coming off. The balls 43 form the fixed connecting means 38 for temporarily fixing the first pipe 31a. When the first pipe 31a is pushed in from the extended state, the ball 43 retracts inward from the hole 44, and the first pipe 31a slides inside the second pipe 31b.

詰められて負傷するおそれはない。According to this embodiment, the upper wheel 2 and the lower wheel 3 are in the open state shown by the solid line in FIG. 4 (A).
The skeleton mechanism including the main rib 4 and the fulcrum 5 is rotatable integrally with the first pipe 31a and the second pipe 31b with respect to the third pipe 31c provided with the hand 6. Therefore, when an external force such as a strong wind is received, the frame mechanism rotates integrally with the first pipe 31a and the second pipe 31b, so that stress is not concentrated on the bone portion and the rocker portion, and there is no risk of damage. . In addition, when the user holds the third pipe 31c or the hand 36 with one hand and pushes up the lower wheel 33 with the other hand, the lower roller 33 forming a part of the frame mechanism opens the umbrella from the closed position D. Until reaching the position U, it does not always rotate on the outer periphery of the second pipe 31b and the first pipe 31a (only rotates integrally), so the finger holding the lower lock 33 for performing the opening / closing operation is the first finger. There is no risk of being injured by being packed between the second pipe 31b or the first pipe 31a and the lower wheel 33.
