To provide a mounting / dismounting apparatus capable of reducing the number of components and simplifying a structure.SOLUTION: A mounting / dismounting apparatus 10 is composed of a pin 11, a case 15, and an operation button 13. The pin 11 has a conical guide part 11a, a columnar contact part 11b, and an annular lock groove 11c from an insertion end side in this order. The case 15 has: an operation button insertion space 15a; a control piece storage regulation space 15ab; a stopper 16 provided in succession to the control piece storage regulation space 15ab; and a pin insertion hole 14 in which the pin 11 is inserted. The operation button 13 integrally has a button body part 13a externally operable and two control pieces 13b opposing each other that are elastically deformable. The opposing two control pieces 13b have: engaging claw parts 20a for locking; engaging claw parts 20b for unlocking; a spring force generation parts 13e; and engaging claws 13g which engage the stopper 16 to stop the operation button 13 at a lock position L when the operation button 13 is pressed back to the lock position L.SELECTED DRAWING: Figure 7
