PURPOSE: To securely wind even a thin object by connecting the support plates for a first and a second pinch roller to each other on the rear of said first pinch roller and forming a guide surface by means of both of the support plates, in a winding device for magnetic tape, etc.

CONSTITUTION: The support plate 101 for a first pinch roller 91 on the belt type object entering side, is supported by a swingable shaft 111 on the opposite side to the entering side, forming a guide surface 1011 for the belt type object. The support plate 102 for a second pinch roller 92 is supported by the first supporting plate 101 using a swingable shaft 112, forming a second guide surface 1021, which is connected to said guide surface 1011. A guide 16 in front of the pinch roller support plate 101 and a guide 17 on the rear of a third pinch roller, are arranged parallel to the tangential line connecting a guide roller 62 to a core 4, spaced with a gap as narrow as possible between each other. Thereby even a thin belt type object can be wound smoothly and securely, without being affected by the curling direction, etc.
