PROBLEM TO BE SOLVED: To provide a shot blasting device for a mid-size product, making the whole equipment small-scale and inexpensive, and making the installation space comparatively small in shot-blasting a mid-size product such as a transmission case. SOLUTION: This shot blasting device includes: a grinding/polishing/cleaning device 1 surrounding the mid-size product for projecting a shot to the mid-size product; a support means 2 entering and leaving the grinding/polishing/cleaning device 1, storing the mid-size product so that the projected shot can collide with the mid-size product, and also rotatable within a vertical plane; and a driving means 3, the base of which the support means 2 is fixed to enter and leave the grinding/polishing/cleaning device 1 and rotate the same within a vertical plane.
