<P>PROBLEM TO BE SOLVED: To provide a plug device that can easily perform the removal and destruction of a plug body for an endoscope. <P>SOLUTION: A portion of an outer periphery of the plug body 28 of a forceps plug 22 is cut out to form an arm 31 having a shape along the circumferential direction of an outer peripheral surface of an opening 21. A tip portion of the arm 31 is formed with a boss 33 that protrudes toward the opening 21. An outer peripheral surface of the opening tip portion 21b is formed with a cam groove 25 for a forceps plug that guides the boss 33. The cam groove 25 for a forceps plug is constituted by a cam groove 35 for attachment that guides the boss 33 when the forceps plug 22 is attached, a cam groove 36 for locking that locks the boss 33, and a cam groove 37 for removal that guides the boss 33 when the forceps plug 22 is removed. When the boss 33 moves along the cam groove 37 for removal, the deflection of the arm 31 exceeds an elastic limit, and the arm breaks. Thus, the removal and destruction of the forceps plug 22 is easily performed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
