PURPOSE: To provide a connector device having a self-aligning function which can surely and smoothly connect a plurality of female parts with a plurality of male parts for disconnectably connecting a plurality of flow passages together.

CONSTITUTION: In order to disconnectably connect a plurality of female parts in a female side block 1 with a plurality of male parts in a male side block, the one of the blocks is movable so that it can come to and away from the other one of the blocks. Both blocks are connected together by a guide mechanism 50 for guiding and positioning the blocks, a resilient supporting mechanism 60 expending in an arbitrary direction orthogonal to a direction in which one of the blocks is moved for connection and disconnection, and a lock mechanism 80 for releasably locking both blocks connected together.
