LOWER MEMBER FIXING DEVICE AND FLUID CONTROL DEVICE PROVIDED WITH THE SAME

摘要

To provide a lower member fixing device that eliminates the need for a fixation tool and reduces the time and effort for fixation, and a fluid control device provided with the lower member fixing device. A through hole of a lower member is formed by a large-diameter section opened in an upper surface and a small-diameter section continued from the lower part of the large-diameter section and opened in a lower surface. A fixation member includes a shaft section inserted into the small-diameter section of the through hole, a head inserted into the large-diameter section of the through hole, and a magnet section provided at a lower end of the shaft section. The support member is made of a magnetic substance and a recess into which the magnet section of the fixation member is fitted is formed in the upper surface of the support member.
