PROBLEM TO BE SOLVED: To release a double belt buckle without adding different release route and release force to a release device in each case of operating an auxiliary operation device, by providing a device for adjusting a length and a force in the auxiliary operation device. SOLUTION: In an auxiliary operation device 4, a cable connected to a double belt buckle is wound around a roll 11 rotatably provided within a connection slide rod 8. Thereby, when an operation lever 5 is operated, the connection slide rod 8 linearly moves to release the double belt buckle. At that time, the roll 11 adjusts a length and a force of the cable. That is, when the double belt buckle is released so that another motion of an end terminal of the cable is prevented, the connection slide rod 8 performs another linear motion so that the cable is rolled around the rotating roll 11. As a result a moving route and a force for releasing the double belt buckle are additionally generated. |
