1. A belt adjusting and holding device configured to adjust a length of at least one belt and hold the adjusted belt, the device comprising:
a device body including:
a belt insertion part formed in a back end portion and opening in a substantially rectangular shape to allow the belt to be inserted forward; and
an opening section having a substantially rectangular shape, communicating with the belt insertion part, and extending through in an upper-lower direction perpendicular to an insertion direction of the belt; and
a belt folding-back member having a substantially plate shape configured to move forward and backward in a front-back direction within the device body, the belt folding-back member comprising:
a folding-back part configured to allow the belt to wind around a front end and fold backward within the opening section; and
a grasping part located on a back end side of the folding-back part and configured to project backward from the belt insertion part together with the folded belt,
wherein the belt insertion part includes an upper inner wall surface and a lower inner wall surface which are formed with standing wall portions rising inward in a stepped shape on a side near the opening section and extending almost continuously in a belt width direction between right and left sidewalls, and
the folding-back part includes an upper end face and a lower end face, at least one of which is formed with a protrusion, which is disposed near a back of the standing wall portion when the belt folding-back member is moved to a backward position, bending the belt into a substantially stepped shape between the protrusion and the standing wall portion, and which is disposed in the opening section when the belt folding-back member is moved to a forward position, releasing the belt from bending.
