Abstract

PURPOSE: To adjust torque without uselessly rewinding a spiral spring when adjusting torque, by mounting stage-surface portions in staircase-like shapes that gradually become high toward the rewinding direction of the spiral spring on an outer circumference of a shaft of a fitting frame.
CONSTITUTION: One end of a spiral spring 4 interiorly installed into an incense box 2 mounted to a fitting frame 1 in a revolution-free shape is fixed to the incense box 2, and the other end is fastened to a shaft 3. Stage-surface portions 6a, 6b... are installed to an outer circumference of the shaft 3 of the frame 1 in staircase- like shapes that gradually become high in the rewinding direction of the spiral spring 4, and connecting concave grooves 7a, 7b..., to which a connecting projection 5 of the shaft 3 can connect, are mounted to each stage-surface portion 6a, 6b.... Thus, torque is adjusted without uselessly rewinding the spring because the connecting projection 5 stops at stages among the stage-surface portions 6a, 6b... even if the shaft intends to turn in the rewinding direction of the spiral spring 4 when torque is adjusted by rotating the shaft 3 under a condition that the torque of the spring is strong.
