<p>A container connector where a rotation prevention mechanism for preventing a rotation shaft from rotating when an upper engagement cone is in an engaged state can always operate normally and smoothly. A rotation shaft (6) is inserted into a shaft insertion hole (5) formed in a connector main body (1), and engagement cones (7a, 7b) are provided on the upper and lower ends of the rotation shaft (6). A stopper insertion hole (31) is formed in the connector main body (1) such that the hole vertically penetrates through a flange (2) and communicates with a hollow chamber (4) in the connector main body (1). A stopper (32) is assembled in the stopper insertion hole (31). A projection portion (33) is provided on the outer periphery of the rotation shaft (6) such that the projection portion faces the stopper (32) in the circumferential direction of the rotation shaft (6) in a state where the stopper (32) is lowered and stopped. The stopper (32) is formed in a spherical shape so that it is smoothly movable in the stopper insertion hole (31) and that the rotation prevention mechanism of the rotation shaft that comprises the stopper (32) and the projection portion (33) always operates smoothly.</p> |
