The position of the stopper ball 6a on the outer peripheral surface side is restricted by a hole formed in the hole formed in the fitting support portion 2b so as not to come off from the outer peripheral surface of the fitting support portion 2b.

The danger display flag member 7 is made of red cloth and formed in a square shape (substantially square in the figure). One end edge of the danger display flag member 7 is attached to the support member 5 in the direction of the outer peripheral axis thereof by bonding or the like. In addition, the opposite end edge side is a free edge, and is normally stored in a rollable state along the outer periphery of the support member 5 so as to be expandable.

The display tube member 3 is made of synthetic resin.
A material having a white fluorescent reflection property (for example, a unitic spark light) is formed in a cylindrical shape having a closed end and longer than at least the fitting support portion 2b and the support member 5 of the gripping member 2, and substantially over the entire outer periphery thereof. (Trade name: engineer grade white) is formed by covering the reflecting portion 3a by means such as sticking.

The display cylinder member 3 is formed such that the inner diameter of the cylinder portion can be fitted into the fitting support portion 2b, and the rear end portion of the display cylinder member 3 has stopper means 6 at the fitting support portion 2b. A stopper hole 8 corresponding to the stopper ball 6a is provided.

Thus, the display cylinder member 3 is gripped with the cover member from the outside so as to cover the flag member 7 with the danger display flag member 7 wound around the support member 5. The member 2 is fitted and supported on the outer periphery of the fitting support portion 2b. In this state, the stopper ball 6a of the stopper means 6 is engaged with the stopper hole 8 of the display cylinder member 3, and
