Therefore, the operation of the one-base lamp 5 can be reliably performed only by the pushing operation, and the positioning of the one-base lamp 5 with respect to the base accommodating portion 6 is performed. FIG. 5 shows a state in which the locking piece 11 rides over the first convex rib 21 and the bottom plate 13 of the base accommodating portion 6 is elastically deformed. Starts to engage with the retaining piece 19, and the tip of the base pin 3 enters the pin insertion hole 25 and starts to contact the contact piece. Then, a change in the rotational power when the vehicle rides over the first convex rib 21 provides a feeling of wearing, that is, a feeling of clicking.

FIG. 6 shows a state in which the locking piece 11 has climbed over the first convex rib 21. At this time, the base accommodating portion 6 is locked in the mounting posture supporting wall 23 to be held in the mounting posture, and the single base lamp is provided. 5 is parallel to the instrument body 30. Further, the projection 1 is engaged with the retaining piece 19 to be in the retaining state, so that the one-base lamp 5 does not come off from the base accommodating portion 6. Further, when the base pin 3 completely contacts the contact piece and power is supplied to the lead wire connection terminal from the lead wire, the lighting becomes possible.

On the other hand, when the one-sided lamp 5 is to be removed, if the one-sided lamp 5 is pulled in a direction in which the tip side of the one-sided lamp 5 is separated from the instrument body 30, the operation moves in the opposite direction to the state shown in FIG. The gold lamp 5 can be pulled out in the direction of arrow Q in FIG. FIG. 7 shows a state in which when the one-base lamp 5 is rotated from the state shown in FIG. 6 to the state shown in FIG. At this time, since the height of the second convex rib 22 is increased, the locking piece 1
Excessive force is absorbed when 1 gets over the second convex rib 22, and no excessive force is applied to the single base lamp 5 so that there is no problem such as breakage. By rotating the cap housing 6 in the opposite direction from this state, the locking piece 11 is
2 can be returned to the lamp attaching / detaching posture of FIG.

According to this embodiment, the base 4 of the one-base lamp 5 is inserted into the receptacle 8 of the base accommodating portion 6, the base pin 3 is passed through the insertion hole 12, and the bottom surface 2 of the base 4 is connected to the base accommodating portion 6. When the base member 13 is pressed against the bottom plate 13, the base housing part 6 rotates about the rotation connection part 10, and the base pin 3 comes into contact with the contact piece, and at the same time, the peripheral side wall 14 hits the mounting posture support wall 23 and the single base lamp 5 is mounted. The posture is established, and the projection 1 is locked to the retaining piece 19. As described above, the base housing portion 6 has the bottom plate 13 in which the insertion hole 12 for inserting the base pin 3 is formed in the container portion 8, and the bottom plate 13 covers the contact piece of the socket body 7. There is no risk of touching the charged part of the vehicle, and safety can be achieved. Further, only by pressing the one-base lamp 5 in the insertion direction, the bottom surface 2 of the base 4 pushes and rotates the bottom plate 13 of the base housing portion 6 to place the one-base lamp 5 in the mounting posture. The position with respect to the portion 6 is securely determined, the projection 1 can be securely locked to the retaining piece 19, and the base pin 3 is supported by the insertion hole 12 when the base housing 6 rotates. Therefore, twisting due to the base pin 3 can be prevented, and an excessive force can be prevented from being applied to the single base lamp or the socket body as in the conventional example, so that the operation of mounting the lamp can be performed simply and reliably.

Since the height H of the cap housing 6 and the height h of the cap pins 3 satisfy H> h, the cap 4 is attached to the cap housing 6.
Is inserted, the position of the base pin 3 is determined by the peripheral wall portion 14, and the base pin 3 is smoothly inserted into the insertion hole 12. Since the insertion hole 12 may be slightly larger than the diameter of the base pin 3, the effect of preventing the charged portion from being exposed is further increased. In the present invention, the holding means for holding the one-base lamp 5 in the mounting position is the first convex rib 21. However, only the frictional engagement between the contact piece and the base pin 3 may be used. The lamp support holding the glass tube of No. 5 may be used.
