摘要： The present invention relates to a vehicular resonator comprising: an outer pipe that constitutes the exterior thereof; an inner pipe, a part of which is inserted into the outer pipe, and which has a slit formed therein as an air movement passage; a movable pipe configured to be able to move inside a resonation chamber formed between the outer pipe and the inner pipe; and an elastic body having one side thereof coupled to the inner pipe and the other side thereof coupled to the movable pipe, thereby providing the movable pipe with an elastic force such that the movable pipe can move.
