Abstract
An IC socket has a socket substrate, an IC press cover pivotally attached to one end of the socket substrate through a shaft, and a lock member pivotally attached to the other end of the socket substrate through a shaft and adapted to engage with and disengage from a free end of the IC press cover. The improvement is characterized in that one end of the socket substrate is formed with a lock member pivot hole for inserting therein the shaft for the lock member adjacent to a press cover pivot hole for inserting therein the shaft for the IC press cover, and the other end of the socket substrate is formed with a press cover pivot hole for inserting therein the shaft for the IC press cover adjacent to a lock member pivot hole for inserting therein the shaft for the lock member. The two pivot holes formed in the above-mentioned one end of the socket substrate are arranged symmetrically with the two pivot holes formed in the other end of the socket substrate.
