Abstract: A suspending strap lodging device allows a suspending strap to be extracted from or withdrawn into a portable object, such as a bag, depending upon whether or not the strap is needed. The device includes a mechanism for allowing the strap to be withdrawn or extracted to a desired length; a locking mechanism for controlling movements of the strap steplessly in both the withdrawing and the extracting directions; and a mechanism for releasing the locking mechanism. The locking mechanism provided in the withdrawing and extracting mechanism prevents the weight of the portable object, or the impact load caused when the object is lifted, from being directly exerted on the strap, thereby enabling the strap to be securely locked in position and allowing it to enjoy a long service life. Also a strap may be equipped with its own strap lodging device. Since it is equipped with a lodging device of its own, this strap can easily replace the straps of existing portable objects.
