PURPOSE:To obtain an inexpensive switching device by sliding the spherical projection of an elastic piece part provided on a slide metallic fitting into a stopper hole bored in a lever holder. CONSTITUTION:A switching lever 6 is moved as shown by an arrow and then a filter fitting tool 1 also rotates arcuately around a pin 3 implanted in the lever holder 2 because a pin 5 implanted in the cut and raised part 6a of the lever 6 is inserted into a long hole 1a pierced to filter fitting tool 1. Further, when the lever 6 is moved as shown by an arrow, the slide metallic fitting 4 also moves at the same time and the spherical projection of the elastic piece part 4c provided to the metallic fitting 4 slides between stopper holes 2b formed in the holder 2, so that the spherical projection part slides in the stopper hole 2b at the time of moving to the stopper hole 2b. Then, the switching operation is completed while the spherical projection part slides in the stopper hole 2b.
