PROBLEM TO BE SOLVED: To provide a slide valve gear in which a slide valve element and a slide valve element housing for housing the slide valve element are easily cleaned, to provide a supply device of powder and granular material, a measuring/transporting device of powder and granular material, and a transport switching device of powder and granular material using the same.;SOLUTION: The slide valve gear 1 performing a transport control of the powder and granular material transported in a transport passage, comprises: a tabular slide valve element 20; slide valve element housings 10, 30; and a slide valve drive part 40 making the slide valve element housed in the slide valve element housing reciprocate. The slide valve element housings are connected with/fixed to the slide valve driving part with locking/fastening tools 50, 60 having manual operation parts 61. When the connection/fixing between the slide valve element housings and the slide valve driving part is released by operation of the manual operation parts, the slide valve element is pulled out of/removed from the slide valve element housings along a slide direction.;COPYRIGHT: (C)2010,JPO&INPIT
