Abstract
A bulb socket (S) has a main body (D) and a restricting projection ( ) is formed continuously on an outer circumferential surface ( ) of the main body (D) over the entire circumference. An O-ring ( ) is fitted on the main body (D) behind the restricting projection ( ). Thus, the restricting projection ( ) contacts the O-ring ( ) during detachment of a bulb socket (S), thereby separating the O-ring ( ) from a sealing surface ( ) of an edge ( ) of a mount hole ( ). Further, the restricting projection ( ) contacts a contact surface ( ) of the edge ( ) during the mounting of the bulb socket (S), thereby preventing the bulb socket (S) from being pushed any further. This prevents the excessive squeezing of the O-ring ( ) and prevents a reduction in its sealing function.
