To realize the widening and storage of a widening part in a specifically-equipped vehicle which can immediately secure a large space.SOLUTION: An expansion mechanism comprises: a first rotor; a second rotor; a chain which is stretched over the first rotor and the second rotor; a first chain support part which is fixed on an end on the widening direction side of a vehicle body and connected to the chain; and a second chain support part which is fixed on an end on the storage direction side of a second widening part that is further widened to the outer side of a first widening part and connected to the chain. When the chain rotates following the rotation of the first rotor and the second rotor, the chain moves in the widening direction together with the first widening part while rotating with the first chain support part as a fulcrum, and the second chain support part moves in the widening direction together with the second widening part.SELECTED DRAWING: Figure 16

    【課題】大スペースを即座に確保することが可能な特装車両において拡幅部の拡幅および収納を実現する。【解決手段】第1回転体と、第2回転体と、前記第1回転体と前記第2回転体とに掛け渡されたチェーンと、前記車体本体の拡幅方向側の端部に固定され、前記チェーンに接続された第1チェーン支持部と、前記第1拡幅部の外側にさらに拡幅される第2拡幅部の収納方向側の端部に固定され、前記チェーンに接続された第2チェーン支持部とを備え、前記第1回転体と前記第2回転体との回転に伴って前記チェーンが回転した際に、前記チェーンが前記第1チェーン支持部を支点として回転しながら前記第1拡幅部と共に拡幅方向に移動し、かつ前記第2チェーン支持部が前記第2拡幅部と共に拡幅方向に移動する。【選択図】図16
