To provide a vehicular interior component mounting structure allowing easy installation, prohibiting easy separation with fingers, and allowing easy removal using a tool.

First clips 21, 21 of an inner member (a cluster inner 2) are inserted into a locking hole 10 of a mounted member (an instrumental panel 10) and locked to a first locked portion 11. In this state, a second clip 30 of an outer member (a cluster outer 3) is inserted into the locking hole 10 and a clip locking member 32 of the second clip 30 is locked to a second locked portion 12 of the mounted member. In this mounted state, a restricting portion (a protruded piece 31c) of the second clip 30 restricts the elastic deformation of the first clips 21, 21 in the direction of approaching each other and restricts the unlock of the first clip 21 from the first locked portion 11.
