PROBLEM TO BE SOLVED: To provide a bulb socket capable of preventing drop of a sealing member from a socket body when the bulb socket is removed, and surely displaying the function of the sealing member in a fitted state. SOLUTION: Since regulating projection part 15 is continuously formed over the whole periphery in the front of a fit O-ring 14 of an outer circumference of a socket body D, and when a bulb socket S is removed, by fitting the regulating projection part 15 to the O-ring 14, the O-ring 14 is separated from a seal surface 16a of an edge part 16 of a fitting hole 11, and when the bulb socket S is fitted, the regulating projection part 15 is fitted to a fitting surface 16b of the edge part 16 of the fitting hole, the pushing operation of the bulb socket S is regulated to prevent the excess crushing of the O-ring 14, and drop in sealing function can be prevented. |
