<p>PROBLEM TO BE SOLVED: To increase the bonding force with a case body without changing the thickness in the height direction of a cushioning material which is an insert parts by providing a detachment preventive means on the side of the cushioning material to absorb the impact on the inside of the case to store a cassette. SOLUTION: An inside plate 27 and an outside plate 28 having a space part 26 for hollow structure are connected to each other like bottom cushioning parts 22, 23, 24, 25, and an upper part is opened in a triangular shape, and a cushioning material 29A which is an insert parts through insert molding is embedded therein. The side of the cushioning material 29A is an inclined surface 29b expanded downwardly. Because the cushioning material 29A is formed in a state where the resin is attached to the side inclined surface 29b, the cushioning material is not easily pulled out upwardly.</p> |
