ることを目的とする。However, in the above-mentioned conventional example, the insulating coating of the power supply line moves due to the frictional resistance when the power supply line is inserted into the hollow portion and moved, and the size of the exposed portion of the core wire changes. However, there is a problem that a situation may occur in which repair is required. Further, when the holder is made of rubber, there is a problem that the exposed core wire breaks through the rubber holder. Further, in recent years, there has been a problem that assembly workability has been remarkably reduced due to downsizing of the discharge lamp and the holder. Therefore, in order to solve the above-mentioned problems of the prior art, the present invention provides a slit or cut that can be opened and closed in the holder, and a portion extending from the slit or the cut to the inner end of the power supply line inside the holder. It is an object of the present invention to improve the assembling workability of the discharge lamp lighting device by placing it in a predetermined position.
