Claims

[Scope of utility model registration request]

A single-cap type lamp having a locking protrusion on the side of the cap from which the lamp pin protrudes; a contact having a fitting recess into which the cap is inserted; a contact that contacts the lamp pin in the fitting recess; and the cap. a socket body having a spring that presses in a direction to push out the fitting recess, and a locking pawl formed in the inner peripheral part of the fitting recess, with which the locking protrusion inserted into the fitting recess locks when the base rotates. , the locking pawl has a locking recess that locks the locking protrusion to prevent it from coming off, and a guide surface that guides the locking protrusion to the locking recess, and further includes a guide surface that guides the locking protrusion on the guide surface. A lighting device characterized in that the guide surface is formed into a convex curved surface so that the inclination of the entrance side end with respect to the rotational direction of the base is larger than the inclination of the locking recess side end of the guide surface.
