 a reel equipped with a frame body, on the outer periphery of which a plurality of symbols are formed;    a driving motor for driving the reel; and    a speed reduction gear for reducing an output from the driving motor, arranged at center of the frame body so that the reel is rotated integrally to the frame body, wherein    an engaging portion is formed radially outside the center of the frame body and an engaged portion to be engaged with the engaging portion is formed at a corresponding position of the speed reduction gear.    
   
   
       2 . The reel unit according to  claim 1 , wherein 
 the engaging portion and the engaged portion are formed at nearly uniform positions in a circumferential direction.    
   
   
       3 . The reel unit according to  claim 1 , wherein 
 the frame body and the speed reduction gear are baffle-fixed by a fitting slot formed at the center of the frame body and a fitting protrusion formed at the center of the speed reduction gear and to be fit in the fitting slot; and    the engaging portion including a plurality of ribs formed to radially outward from a circumferential wall defining the fitting slot, and the engaged portion including a plurality of recesses to be fit over the plurality of ribs, respectively formed around the fitting protrusion of the speed reduction gear.    
   
   
       4 . The reel unit according to  claim 1 , wherein 
 the frame body and the speed reduction gear are baffle-fixed by a fitting slot formed at the center of the frame body and a fitting protrusion formed at the center of the speed reduction gear and to be fit in the fitting slot; and    the engaging portion includes a recess formed to radially outward from a circumferential wall defining the fitting slot; and    the engaged portion includes a rib to be fit over the recess formed around the fitting protrusion of the speed reduction gear.    
   
   
       5 . The reel unit according to  claim 1 , further comprising 
 a circumferential wall defining a fitting slot formed at the center of the frame body, wherein    the engaging portion is defined in an outer peripheral surface of the circumferential wall.    
   
   
       6 . A gaming machine comprising 
 a reel unit, wherein    the reel unit comprises:    a reel equipped with a frame body, on the outer periphery of which a plurality of symbols are formed;    a driving motor for driving the reel; and    a speed reduction gear for reducing an output from the driving motor, arranged at center of the frame body so that the reel is rotated integrally to the frame body, wherein    an engaging portion is formed radially outside the center of the frame body and an engaged portion to be engaged with the engaging portion is formed at a corresponding position of the speed reduction gear.
