PROBLEM TO BE SOLVED: To enhance separation prevention performance without adding a separate member, which prevents the separation of a spring pin connecting the operation member of a container and an opposite member to it, and a separation preventing structure to the outside of a pin hole serving as an opening from which a pin starts to be inserted.SOLUTION: A member connection structure for connecting a handle 4 (operation member) and a shoulder member 2 (opposite member) by inserting a spring pin 5 in the pin holes 2a and 4a of these members 4 and 2 in the direction of the pin length is formed so as to be mirror symmetrical in the direction of the pin length. The range of the relative displacement between the handle 4 and shoulder member 2 in the direction of the pin length is limited by the butting of the members 2 and 4. An empty space 7 is reliably defined in the direction of the pin length by forming a wall portion 4c receded from a butting wall 4b in the direction of pin insertion between the periphery of the exit of the pin hole 2a, serving as an opening from which the pin starts to be inserted, and a wall portion 4c defining the pin hole 4a opposite to the exit of this pin hole 2a. A spring pin 5 is formed with a projecting portion 5b, which is located in the empty space 7 and is caught by the periphery of the exit of the pin hole 2a in the opposite direction to the direction of the pin insertion. |
