A guide protrusion is provided approximately in the center of the main plate portion to be inserted into the swidth hole, and a screw is screwed into a boss protruding from the guide protrusion toward the back surface of the guide protrusion. The back surface of the head is locked to the edge of the slide hole, and a lip is formed on the outside of the concave surface by providing a concave surface on at least the inner side and both sides of the guide convex part in the main plate part. The globe attachment device for a lighting device is characterized in that the slide hole is closed by the main plate portion when the device slides outward.

According to the present invention, since the neck portion and the guide convex portion of the operating portion of the slide piece are always guided by the slide holes of the chassis, it is possible to smoothly slide the slide piece with good linearity, and the operation portion and Since the heads of the screws are always engaged with the edges of the slide holes, the slide pieces can slide smoothly without tilting.

In addition, the boss protruding from the back side of the guide convex part to engage the screw can prevent the right side of the slide piece of the synthetic resin from warping away from the slide hole at least in the main plate part. A concave surface is provided on the inside of the convex portion and on both sides, and a lip is formed on the outside of the concave surface.This lip corrects the warpage and improves the planar deformation of the main plate, thereby improving the connection between the main plate and the chassis. Since they are close to each other with almost no gaps, there is no risk of small insects entering the chassis through the slide holes 75).
