Patent ID: 7481903

Claim:
A mechanism for assembling plasma processing device parts, the mechanism comprising: a first member comprising a plurality of fixing pin configured to pivot between a first position, at which the fixing pin projects in a first direction, and a second position, at which the fixing pin inclines in an oblique direction with respect to the first direction; a second member defining a plurality of pass-through holes configured to receive a fixing pin, each pass-through hole comprises a first projection configured to provide a fulcrum when a fixing pin moves from the second position to the first position by relatively moving the first member and the second member in a locking direction, and a second projection configured to provide a fulcrum when the fixing pin moves from the first position to the second position by relatively moving the first member and the second member in an unlocking direction; and a groove side member defining a plurality of grooves configured to receive a fixing pin, wherein the mechanism is configured such that when the fixing pins are passed through the pass-through holes defined in the second member and into the grooves defined in the groove side member, rotating the first member relative to the second member and the groove side member results in the fixing pins pivoting from the second position to the first position, thereby locking the first member the second member, and groove side member with respect to one another.
