At this time, the profile main body 21 and the support portion 22 may be integrally formed, or may be formed separately and then fixed to each other. Moreover, after forming the profile precursor which does not have the space 22V and the insertion port 22z, the profile 20 may be produced by cutting the space 22V and the insertion port 22z on the profile precursor.

  In the attaching step S3, the profile 20 is attached to the belt body 10 by inserting a part of the belt body 10 in the longitudinal direction of the belt in the belt width direction through the insertion port 22z and fitting it into the space 22V. At this time, a part of the belt body 10 in the belt longitudinal direction is inserted into the insertion port 22z from one end in the belt width direction (a part including the other side surface 10z2) while being slightly bent in the belt width direction. In the process in which the part is moved in the belt width direction with respect to the space 22V, the back surface 10y and the inner surface 10x are respectively a portion defining an insertion port 22z in the first side surface support portion 22c and an insertion port in the inner surface support portion 22b.

Since the insertion port 22z has the same size as the thickness D of the belt body 10, the profile 20 is unlikely to come off the belt body 10 when the belt with profile 1 is driven.

  Further, the belt body 10 is sandwiched in the belt thickness direction by the back surface support portion 22a and the inner surface support portion 22b, and the belt body 10 is sandwiched in the belt width direction by the first side surface support portion 22c and the second side surface support portion 22d. In addition, since the size of the insertion port 22z is equal to the thickness of the belt body 10, the profile 20 is fixed to the belt body 10 without backlash in both the belt width direction and the belt thickness direction. Can do.
