1 . An infant bathing assistance device configured to enable an infant to stay upright without falling when a guardian bathes the infant, the infant bathing assistance device comprising:
 an upper body part configured to support an upper body of the infant;   armrests each configured to support an arm portion or an armpit portion of the infant so as to enable the infant to stay upright; and   a lower body part formed on a lower side of the upper body part, the lower body part being configured to support a lower body of the infant,   wherein the armrests rotatably formed on the upper body part are rotated in an inward direction to reduce a space between the armrests or are rotated in an outward direction to increase the space therebetween,   the infant bathing assistance device comprising a rotation control means configured to restrict rotation of the armrests in one of the inward and outward directions,   wherein the rotation control means comprises a fixed wheel, a rotating wheel, and a stopper interposed between the fixed wheel and the rotating wheel to perform a constricting action.   
     
     
         2 . The infant bathing assistance device according to  claim 1 , wherein the constricting action is performed through a process of reducing a gap between pressing areas of the fixed wheel and the rotating wheel, a process of increasing a gap between two pressing areas of the stopper, or a process of simultaneously performing the two processes. 
     
     
         3 . The infant bathing assistance device according to  claim 1 , wherein the stopper is in point contact, line contact, or surface contact with the fixed wheel and the rotating wheel. 
     
     
         4 . The infant bathing assistance device according to  claim 1 , wherein the stopper is formed as a single body or is formed of a plurality of components combined with each other. 
     
     
         5 . The infant bathing assistance device according to  claim 1 , wherein at least one of the pressing areas of the fixed wheel, the rotating wheel, and the stopper has an uneven portion formed thereon. 
     
     
         6 . The infant bathing assistance device according to  claim 1 , further comprising a contact-maintaining means configured to enable the stopper to maintain contact with the fixed wheel and the rotating wheel. 
     
     
         7 . The infant bathing assistance device according to  claim 6 , wherein the contact-maintaining means is an elastic body or a magnetic body. 
     
     
         8 . The infant bathing assistance device according to  claim 1 , wherein the rotation control means comprises a positioning means configured to set an operating range of the stopper such that the stopper is moved within a predetermined range. 
     
     
         9 . The infant bathing assistance device according to  claim 8 , wherein the positioning means is a side wall of a concave groove formed in the fixed wheel or the rotating wheel or a guide ring formed between the fixed wheel and the rotating wheel. 
     
     
         10 . The infant bathing assistance device according to  claim 1 , wherein each of the armrests has a rotation shaft provided therein, and each of the armrests and the rotation control means are selectively operated in conjunction with each other depending on an axial position of the rotation shaft. 
     
     
         11 . The infant bathing assistance device according to  claim 10 , wherein a locking groove  525  is formed in a central portion of rotation of the rotating wheel, a locking protrusion  630  is partially formed on an outer circumferential surface of the rotation shaft, and the locking groove and the locking protrusion are selectively coupled to each other depending on the axial position of the rotation shaft.
