DEFINITION

Classification: 29/434

Retaining clearance for motion between assembled parts:

(under subclass 428) Process in which the parts are finally assembled to provide a tolerance space or clearance of fit sufficient to permit movement with respect to each other in the assembled relationship.

(1) Note. In this subclass may be found parts which when assembled have sliding, pivoting, or rotating motion, one with respect to the other.
