Abstract: PURPOSE: To economize the manufacture of a cassette and to prolong the service life of the cassette by using an elastically deformable material for at least a part of a rocking element and also arranging a restraining device so as to enable the rocking operation. CONSTITUTION: At least a part of the rocking element 10 capable of rocking around a supporting axial line B of supporting devices 6A, 6B consists of the elastically deformable material, and the restraining devices 41, 42 are arranged so as to enable the rocking operation. A supporting protrusion 13 on the upper supporting axial line B and/or a lower part 19 of the supporting axial line B is brought into contact with the inside of an outer wall 15 in the unoperating position 10 substantially without stress. When the restraining device 42 is operated to the operating position 10", the rocking element 10 is rocked and moved to the tightened state, and the supporting protrusion 13 is brought into contact with the inside of the casing wall 15, and also the lower side part 19 is made not in contact therewith. Thus, the manufacture of the cassette is economized and the service life of the cassette is prolonged.

Abstract: PURPOSE: To obtain a linear spring characteristic by providing a flat spring in a middle range continued to two spring arms curved in curved lines and as a fitting device, an opening and a recessed fitting collar around this opening. CONSTITUTION: This tape cassette is provided with a casing 11 fitted with the pressing springs 15 and 25 in the middle of a large wall and one or plural magnetic tape reel(s) loaded elastically by the pressing spring 25 toward its operating position. In this case, the pressing springs 15 and 25 consist of curved spring strips having the same width, and the fitting devices are provided at an interval in the middle range 20 of the springs respectively on their flat surfaces. Then, the two spring arms 21 and 22, each having the flat spring middle range 20 followed by the continuous part curved in the curve line (r), and as their fitting devices, at least one of the openings 16 and 24 and the recessed fitting collars 17 and 23 around these openings are further provided. By this method, the optimum spring characteristic can thus be obtained.
