Claims

[Scope of utility model registration request]

In a light source holding device that holds a straight tube type light source having electrodes protruding in the outer circumferential direction at both ends, an insertion path is formed in the light source holding device main body so that the light source can be inserted from the tube axis direction, and the insertion path is Electrode plates connected to the light source are disposed at both ends in the tube axis direction, and the insertion path is in an insertion position in which the electrodes of the light source are oriented vertically and are located in front of the electrode plates in the insertion direction. A rotation permissible space portion is formed that allows switching from the posture to a fixed posture rotated by 90 degrees around the tube axis, and a biasing means is provided for biasing the electrode in the fixed posture toward the electrode plate side in the tube axis direction. A light source holding device characterized in that the electrode plate is formed in a concave shape with respect to the biasing direction so as to be biased by a biasing means and to position the electrode in the vertical direction.
