In addition, in the running process of the vehicle, since the vehicle lamp 100 is generally connected with the vehicle body, the vibration of the lamp housing 1 can be well buffered through the rubber sleeve 3, so that the vibration transmitted to the ventilation cap 4 can be well reduced, and further, the loosening and falling-off of the ventilation cap 4 can be well avoided, thereby being beneficial to ensuring the firm installation of the ventilation cap 4.
