Abstract
A sliding contact is formed by a first terminal 40 fixed to a side of a lamp base flange 2 and a second terminal 41 fixed to a side of a slider 7. Accordingly, it is possible to supply an electric current to a glass tube 9 without bending a harness 3. Therefore, a harness 3 is not deteriorated, and a resistance at a time of sliding the glass tube 9 is not increased.
