<p>A cable seal fitting (420) is a seal fitting configured to seal a portion of an inner wire (78) that is connected to a gear change assisting mechanism having a casing (400) that can be mounted to a bicycle, the portion of the inner wire (78) being the portion that moves into and out of the casing (400). The seal fitting 420 includes a mounting member (421) and a seal member (422). The mounting member (421) has a fastening portion (431) that is provided on the base end of the mounting member (421) and can be fastened to the casing, and an inner wire guiding passage (432) that is provided inside the fastening portion (431) such that the inner wire (78) can pass there-through from the base end toward the tip portion of the mounting member (421) and is configured such that its diameter widens toward the cable-operated device. The seal member has an attaching portion (435) that is mounted in a closely fitting and freely detachable manner to the tip portion of the mounting member (421), and a seal portion (436) through which the inner wire (78) passes. The seal portion (436) has a large-diameter section (440) that communicates with the inner wire guiding passage (432), and a contact section (441) that has a smaller diameter than the large-diameter section and is configured to contact the outside surface of the inner wire (78).
