Cell frame for retaining flat-shaped electrochemical cell of battery in motor car, has circular tie rod operation unit comprising inner peripheral support surface in which circumferential projection is constructed and arranged

摘要

The frame has a circular tie rod operation unit (15) arranged at corner regions of the frame and vertically to a base part (12) of the frame for guiding a tie rod. The circular tie rod operation unit has a circumferential projection (21) exhibiting a sleeve i.e. insertion sleeve, made of metal or metallic alloy, and an inner peripheral support surface in which the circumferential projection is constructed and arranged. The tie rod operation unit comprises an upper bearing support surface for engaging a collar of the sleeve.
