[Brief explanation of the drawing]

Figure 1 is a plan view showing one embodiment of the present invention;
The figures are cross-sectional views taken along the line X-X in Figure 1, and Figures a, b, and c in Figure 3.
are side views showing the ballast used in the above, respectively;
A plan view, a front view, FIG. 4 is a perspective view showing the stabilizer used in the above, FIGS.
A side view, FIG. 6 is a graph showing an example of the above experimental results, and FIG. 7 is a partially cutaway front view showing a conventional example.
FIG. 8 is an explanatory diagram of the operation of the same ballast as described above, and FIG. 9 is an enlarged view of section A in FIG. 7. 1 is a device main body, 5 is a stabilizer, 6 is a terminal, 7 is a convex portion, and 8 is a convex portion.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) In a structure in which the ballast is attached to the device body in such a way that the terminal forming surface of the ballast is in contact with the device body, the ballast is located opposite to the ballast at a position corresponding to the terminal of the ballast. A mounting structure for a ballast in a lighting fixture, which has a convex portion that protrudes to the side formed on the fixture body. (2) In the mounting structure of a ballast in a lighting equipment as described in claim 1 of the utility model registration claim, where the ballast is a leakage transformer type ballast, the protrusion height of the convex portion at the position corresponding to the pass gap is The protrusion height is set to an extent that vibration is smaller than the maximum vibration when the surface opposite to the terminal forming surface is brought into contact with the device body. (3) A mounting structure for a ballast in a lighting fixture as set forth in claim 1 of the utility model registration claim, in which a protrusion protruding toward the ballast is formed between a pair of adjacent protrusions.
