<P>PROBLEM TO BE SOLVED: To provide a vehicular lamp capable of preventing or restraining cloudiness in a lamp chamber by effectively utilizing an existing space around the lamp. <P>SOLUTION: Since a rear-side opening 26 allowing a light source 30 to be introduced and extracted therethrough is formed on a housing 22, and a back cover 42 sealing the rear-side opening 26 is provided with an extensible part 50 capable of absorbing pressure change in the lamp chamber 40, the pressure change in the lamp chamber 40 can be absorbed by using an existing space 60 for light source replacement located in the outside of the lamp chamber 40 when viewed from the rear-side opening 26. Since it is not necessary to form a breathing hole like a conventional one in the housing 22 by providing the extensible part 50 for the back cover 42, and the sealing state in the lamp chamber 40 is kept by sealing the rear-side opening 26 by the back cover 42, intrusion of wet air outside the lamp chamber 40 can be effectively prevented or restrained. <P>COPYRIGHT: (C)2008,JPO&INPIT |
