2. Description of the Related Art Conventionally, a lighting device has been used for taking a photograph indoors. Usually, the lighting device is mounted on a T-shaped arm on a vertical rod planted on a base member constituting a lighting stand. It is fixed and mounted so that it can be freely turned.

This vertical rod is divided into two parts, for example, and is slidable (expandable and contractible) in the vertical direction, and the sliding amount (extended and contracted amount) is screwed from the outside of one of the vertical rods. By screwing the knob bolts, the other vertical rod can be arbitrarily held, so that the knob bolts protrude largely outside each vertical rod.

Further, the lighting device can move the lighting device main body to which the cord is connected in an arbitrary direction and position so as to be held by the T-shaped arm. The lighting fixture is enabled by being plugged into a power outlet.

[0005] The first vertical rod and the vertical rod are
Since the inside diameters are relatively small and the amount of mutual sliding can be performed over substantially the entire length thereof, the height of the arm, that is, the height of the lighting device can be arbitrarily increased with a large width. It can be adjusted.

In general, a circular pipe is used for such a vertical rod, and therefore, it is easy to rotate or change the direction of the upper vertical rod while the lower vertical rod is fixed. Therefore, there is an advantage that the direction of the lighting fixture can be arbitrarily selected.

There has been a problem that an accident such as a person falling down by catching a foot may be caused.

In addition, since the vertical rods are substantially equal in length to each other and slide over substantially the entire length thereof, it is tentatively attempted to secure a storage space for a cord or the like in the cylindrical portion of the vertical rod. However, this could not be secured, and as a result, the cord was used in a state of being hung down from the lighting fixture as described above, resulting in the above-mentioned fall accident and the like.
