BACK DOOR

摘要

A back door (20) for closing, in an openable manner, an opening formed in the rear end part of a vehicle, and for covering lamps (60) disposed on the periphery of the opening from the rear side when in a closed state in which the opening is closed. The back door is provided with: an inner panel (30) having a translucent part (33) which allows light emitted rearward from a lamp (60) to pass therethrough; a light-transmission part (41) which is disposed so as to face the translucent part (33) from the rear side with a gap therebetween, and which allows the outgoing light passed through the translucent part (33) to transmit toward the rear side; and a light guide body which is disposed in a space (S) formed between the translucent part (33) and the light-transmission part (41), and which introduces the outgoing light passed through the translucent part (33) to the light-transmission part (41).
