PROBLEM TO BE SOLVED: To provide a card type driving device which can assure large bonding strength with an adhesive sheet, and exhibits an excellent dust-proofing action by the adhesive sheet. SOLUTION: A cover 2 to cover the outer surface of a chassis 1 is attached on the chassis 1. Adhering surfaces 22a and 22b at the side of the cover 2 formed over the whole peripheral edge part of the cover 2 and an adhering surface 12 at the side of the chassis 1 formed over the whole peripheral edge part of the chassis 1 are adhered by using the adhesive sheet 3. A projected line 23 is formed on the adhering surfaces 22a and 22b at the side of the cover 2, a recessed line 13 is formed on the adhering surface 12 at the side of the chassis 1, and then the projected line 23 and recessed line 13 are fitted. The adhesive sheet 3 which sticks the adhering surfaces 22a and 22b at the side of the cover 2 to the adhering surface 12 at the side of the chassis 1, sticks the recessed line 13 to the projected line 23 also in the fitting part of the recessed line 13 and the projected line 23.
