PURPOSE: To decrease the height of a titled reel turntable and to reduce the thickness of the structure of said reel turntable with simple constitution, by forming a clutch hollow-out part to the lower surface of a clutch bar and setting the upper end part of a clutch spring into said hollow-out part.

CONSTITUTION: A hub 3 of a cassette half 1 is put on a cap 10 and pressed. Thus the hub 3 is guided smoothly by a tapered end face of the cap 10, and assured engagement is secured among a projected part 3a, a depressed part 3b and a clutch projected part 8a. In this case, the distance of displacement is secured for fitting of a clutch bar 8 for the height of displacement of the bar 8 since the upper end of a clutch spring 9 is set inside from the lower surface of the bar 8 by an amount equivalent to the depth of a clutch hollow-out part 8b. In such constitution, the height of a reel turntable is reduced by an amount equivalent to the depth of the part 8b with a simple structure, thereby attaining reduction in thickness of the reel turntable.
