The lower buckle ring 314 can be engaged with and disengaged from the lower engaging portion 332 of the lower connecting member 33 in a state in which the lower end side of the outer elastic band 311 is inserted from the outside.

図２に示したように、下バックルリング３１４を下係止部３３２から外した場合には、牽引部３０の全体の弾性係数（Ｋ）は、外側弾性帯３１１の弾性係数（Ｋ１）となる（Ｋ＝Ｋ１）。また、図３に示したように、下バックルリング３１４を下係止部３３２に係止させた場合には、牽引部３０の全体の弾性係数（Ｋ）は、外側弾性帯３１１の弾性係数（Ｋ１）と、内側弾性帯３１２の弾性係数（Ｋ２）の合計となる（Ｋ＝Ｋ１＋Ｋ２）。すなわち、下バックルリング３１４を下係止部３３２から係脱させることで、牽引部３０の伸び量に対する張力Ｔを簡単に変更することができる。これにより、着用者の体力や作業内容等に応じて、牽引部３０の張力Ｔやアシスト力を最適に調整することができる。 As shown in FIG. 2, when the lower buckle ring 314 is removed from the lower locking portion 332, the elastic modulus (K) of the entire pulling portion 30 becomes the elastic modulus (K1) of the outer elastic band 311. (K=K1). Further, as shown in FIG. 3, when the lower buckle ring 314 is engaged with the lower engaging portion 332, the elastic modulus (K) of the entire pulling portion 30 is equal to the elastic modulus (K) of the outer elastic band 311 ( K1) and the elastic modulus (K2) of the inner elastic band 312 (K=K1+K2). That is, by disengaging the lower buckle ring 314 from the lower locking portion 332, the tension T with respect to the extension amount of the traction portion 30 can be easily changed. Thereby, the tension T and the assisting force of the pulling portion 30 can be optimally adjusted according to the physical strength of the wearer, the type of work, and the like.

また、外側弾性帯３１１の弾性係数（Ｋ１）を、内側弾性帯３１２の弾性係数（Ｋ２）よりも大きく設定すること（Ｋ１＞Ｋ２）が好ましい。これにより、調整可能な張力Ｔの範囲を狭めてアシスト力の微調整を行うこともできる。 Further, it is preferable to set the elastic modulus (K1) of the outer elastic band 311 to be greater than the elastic modulus (K2) of the inner elastic band 312 (K1>K2). As a result, the range of adjustable tension T can be narrowed, and the assist force can be finely adjusted.
