A structure of instrument panel parts is proposed that is capable of increasing the support strength of a striker and the rigidity of an opening portion, and with which an enlarged storage volume can be achieved. The structure of an instrument panel has a storage portion arranged above a glove box. The structure includes an opening portion for a tray provided above the glove box; a tray constituting the storage portion, the tray being provided as a separate member from the instrument panel and being attached to the opening portion for the tray; a striker engaging a lock of the glove box; and a substantially flat plate-shaped striker reinforcement member supporting the striker. The lower side of the tray and the striker reinforcement member are fastened together to the instrument panel.
