<p>Provided is a web guiding apparatus capable of ensuring a smooth operation and durability against a force applied from a web even if the apparatus is used in an environment with airborne paper powder, dust and the like. The web guiding apparatus includes a rocking frame 4 rocking around an axis perpendicular to a reference surface 2s of the base 2, and a support portion 40 supporting movement of the rocking frame 4 with respect to the base 2. The support portion 40 includes a base member 41 provided on the base 2 and having a rolling surface parallel to the reference surface 2s of the base 2, and a roller 46 provided on the rocking frame 4 so as to roll on the rolling surface of the base member 41. The rolling surface of the base member 41 is formed so that an axial direction thereof intersects an arc with a rocking shaft 3 of the rocking frame 4 as a center. A width of the roller 46 is wider than a width of the rolling surface of the base member 41. The roller 46 is provided so as to move along the arc with the rocking shaft 3 of the rocking frame 4 as the center when the rocking frame 4 rocks.</p> |
