SHEET WINDING DEVICE AND ASSEMBLING METHOD OF SHEET WINDING PART

Japanese Patent JP2014226969

A

PROBLEM TO BE SOLVED: To provide a sheet winding device and an assembling method of a sheet winding part capable of preventing or suppressing the occurrence of abnormal sound caused by the striking of a coil spring to a winding pipe via a silencer.SOLUTION: A silencer 42 which is flexible and has a quadrate and square cylindrical shape is interposed between a winding pipe 30 and a coil spring 40. The silencer 42 has each edge center part 42S as a spring adjacent part 44 which is brought into contact with an outer circumferential surface of the coil spring 40 and is bendable and has a corner part 42C as a pipe adjacent part 46 supported by a female spline part 32 of the winding pipe 30. When shrinking the diameter of the coil spring 40 by square turns, the silencer 42 can be elastically returned to such a shape as to reduce deflection amount of the spring adjacent part 44, thereby, decrease the diameter D1 of an inscribed circle C1 at a cross-section in the axis orthogonal direction of itself and increase the diameter D2 of a circumscribed circle C2 at a cross-section in the axis orthogonal direction of itself.
