<p>PURPOSE: To make a tentative tacking rib for tentatively tacking a tape cassette so as not to be broken by an impact. CONSTITUTION: The tentative tacking rib 15 consisting of a pair of elastic rib pieces 15a, 15b is erected in a bottom surface part 8, and the tape cassette 1 is tentatively tacked by inserting a pair of elastic rib pieces 15a, 15b to a tentative tacking hole 7 of the tape cassette 1 in the state deformed with deflection. The space D between a pair of elastic rib pieces 15a and 15b is, when either one elastic rib piece 15a or 15b is deformed with deflection until the state bringing into contact with another elastic rib piece 15b or 15a, set to such dimension that the deformation of a base of one elastic rib piece 15a or 15b does not exceed the limit of elasticity.</p> |
