In the present invention, it is made of a synthetic resin transparent body, A diamond cut is applied to the inner surface of the colored LED light-emitting body (signal LED 14 described later) arranged in the light-emitting section 2 with directivity set so that the light emission is diffused in all directions in combination with refraction. It is configured. It is essential that the light emitting unit 2 is a light-transmitting body as described above, but it is optional to make it colored.

If necessary, a light source 4 for illuminating white light with a widening light angle, which is a light emitting body of a different type from the signal LED 14, may be installed at the tip of the light emitting portion 2. In the case of the illumination light source 4 having no light, the widening lens portion 5 may be provided at the tip of the light emitting portion 2.

The grip portion 3 connected to the rear end of the light emitting portion 2 is formed on the same coaxial line as the light emitting portion 2 in the front, and the inside thereof is mainly used for the power source 6 such as the dry battery 6a and the wiring space and the like. Is allocated.

A casing 1 including these light emitting portions 2
And a lid 9 described later, together with acrylic resin, vinyl chloride resin, polypropylene resin, polyethylene resin,
A synthetic resin such as a polycarbonate resin is used as a material, and a flexible material is selectively adopted even at least only in the grip portion 3, and the grip portion 3 and the light emitting portion 2 are formed into a cylindrical shape to be strong. The casing 1 is united to form one casing 1.

Further, by incorporating the dry battery 6a, the center of gravity of the entire body is biased toward the grip portion 3 and, if it is accidentally dropped, the landing is performed from the grip portion 3 due to the bias. Since the casing 1 including the grip portion 3 in which the lid 9 is united is made of a highly flexible synthetic resin, for example, a resin having both flexibility and toughness such as a polycarbonate resin, it may be dropped. It is designed so that it is possible to avoid shock and damage that leads to destruction of the whole.
