Claim:
A microgripper device for a micro-mechanism, comprising: a microactuator member being a V-shaped member symmetrically arranged about a longitudinal direction of the microgripper device, an end of the microactuator member provided with an actuating portion to output a driving force; and a microgripper member including a main frame, an engaging portion, a pair of lateral shifting portions and a gripping portion which are arranged along the longitudinal direction, the main frame accommodating the microactuator member while the engaging portion engaging with the microactuator, each of the lateral shifting portions linking the main frame, the engaging portion and the gripping portion to constitute an interconnected relationship; wherein the microgripper member is used to generate a gripping or releasing movement, when the driving force of the microactuator member actuates the engaging portion of the microgripper member, the gripping portion of the microgripper member generates the gripping movement; wherein when the driving force of the microactuator member is removed from the engaging portion of the microgripper member, the gripping portion of the microgripper member generates the releasing movement.
