Abstract
To provide an IC socket which reduces the operating force of a pressing member, enlarges the dimensions of a pressing surface of the pressing member, and prevents positional offset of the IC device while applying the pressing force. Means for Solution: An IC socketis provided with a housinghaving a support, a plurality of contacts, a pressing memberfor pressing an IC device supported at the support toward a group of contacts, and a biasing mechanismfor generating a pressing force for pressing the IC device at the pressing member. The pressing member has a pivotguided linearly on the housing and a pressing surface swingable about the pivot on the housing, while the biasing mechanismapplies a biasing force to the pivot of the pressing member so as to cause the pressing force at the pressing surface. The pressing surface of the pressing member moves in parallel displacement between an operating position where it is closest to the support and a first nonoperating position where it is away from the support and swings between the first nonoperating position and a second nonoperating position further away from the support.
