[Problem] To make it possible to exchange dispersed-salt-collecting gauze within an instrument shelter automatically or through a simple operation. [Solution] A retaining device 100 is configured so that when an upper part 110 and lower part 130 rotate together around an axis of rotation 146, the retaining device 100 alternates between a first state in which an unused dispersed salt collector 20 falls, through slits 112E, 144B, from one of a plurality of retaining frames 114 of the upper part 110 to a retaining frame 124 of an intermediate part 120 and is placed on top of a lower part 130 and a second state in which a dispersed salt collector 20 in use falls, through slits 143B, 132F, from the retaining frame 124 of the intermediate part 120 to one of a plurality of retaining frames 134 of the lower part 130 and an unused dispersed salt collector 20 is placed on an intermediate upper plate 144. |
