A strap device 15 has guides 3, 5 in which slits 7b, 7a, 9a, 9b are formed with central members 3b, 5b intervening therebetween. First ends of straps 11, 13 are secured to the central members 3b, 5b respectively. A second end 11b of the strap 11 passes through the slits 9a, 9b of the guide 5, and then the second end 11b passes through the slit 7a of the guide 3. A second end 13b of the strap 13 passes through the slits 7a, 7b of the guide 3, and then the second end 13b passes through the slit 9a of the guide 5. When the second ends 11b, 13b are pulled out in mutually opposite directions, the strap, which has a quadruple length as compared with the spacing distance between the guides, can be instantaneously pulled out. When the strap device 15 is used for a shoulder strap, it is possible to provide a bag which has a good appearance and which is excellent in functionality and safety. <IMAGE> |
