Abstract: An electromagnetic contactor includes a contact mechanism having a pair of fixed contacts disposed to maintain a predetermined interval in a longitudinal direction, and a movable contact disposed above the pair of fixed contacts, the movable contact contacting to and detaching from the pair of fixed contacts. Each of the pair of fixed contacts has a fixed contact portion, the movable contact extends in a longitudinal direction thereof and has a pair of movable contact portions contacting the pair of fixed contacts, and the movable contact is disposed so as to move in a vertical direction thereof on a connecting shaft fixed to a movable plunger and is pressed down by a biasing force of a contact spring in a downward direction thereof on a central portion of the movable contact in the longitudinal direction, the movable contact being held on the connecting shaft.

Abstract: The present invention is associated with a recording medium in which, to a data part constituted by frames obtained by attaching a synchronous signal to the data divided by a predetermined data length, data having a preamble part and a postamble part attached with at least one synchronous signal having a pattern different from that of the synchronous signal attached to the data part are recorded, a reproducing apparatus for reproducing this recording medium, and a recording apparatus for recording data to this recording medium.
