PURPOSE: To easily separate two integrally joined members by operation from the outside by providing a separation means through the means of an expansible coupler, etc., in the inside of a snap-fit device to join two members of arbitrary shapes. CONSTITUTION: An element 5, vertically projected from an end surface 3 of one member 2, is installed in a recessed part provided on an end surface 4 of the other member 1 and is engaged with a recessed part surface by elastic return of the element 5. Thereafter, engagement with the recessed part is released against elastic returning force of the element 5, by providing a separation means free to operate from outside in the inside of a device. As this separation means, a method to interpose expansible couplers 9, 9' between the element 5 and the recessed part and to expand them by supplying motive force from a motive force source, etc., are adapted. |
