The present invention relates to a vehicle tray and, more specifically, the objective of the present invention is to prevent a cover slidably provided inside a tray body from moving by vibration generated when a vehicle travels and, simultaneously, to prevent, in advance, the generation of friction noise when protrusions come into contact with guide rails provided in the tray body even when the cover is operated. The present invention comprises: a tray body (100) having an accommodation part (110) of which the upper side is open; the guide rails (300) fixedly provided, respectively, at both the left and right sides of the accommodation part (110); and a cover (200) having the guide protrusions (210), which are formed to respectively protrude from both the left and right sides thereof and slide while being guided along the guide rails (300). In order to achieve the present invention, protrusion parts (211) having mounting grooves (211a) protrude from the front and rear end portions of the guide protrusion (210) of the cover (200), and a silicone ring (400) having elastic force itself and having an outer surface coming into contact with the inner wall surface of the guide rail (300) is provided at the protrusion part (211) in a state in which the inner surface thereof is mounted in the mounting groove (211a).
