摘要： A movable hook portion (13) provided in a unit side coupling surface (2a) of an accessory unit (2) includes a hook portion main body (14), which is formed with a movable claw (23a) and a pressed piece (22), and a straight spring (15), slidably accommodates the hook portion main body (14) in a main body accommodation concave portion (16) formed in the unit side coupling surface (2a), and accommodates the straight spring (15) in a spring accommodation concave portion (17a) formed in the unit side coupling surface (2a) so as to be orthogonal to a sliding direction of the hook portion main body (14), with a middle portion in a length direction of the spring being engaged with the hook portion main body (14). When the hook portion main body (14) is slid in a disengaging direction which brings the movable claw (23a) and a hooking hole (8a) of an electromagnetic contactor (1) into a disengaged state by pressing the pressed piece (24), an elastic restoring force of the straight spring (15) elastically deformed into a bow-like shape acts on the hook portion main body (14) in a direction opposite to the disengaging direction.

摘要： An extinction cover 5 is mounted on a case 4 thereby sealing an extinction chamber S. This extinction cover has an engaging-force-increased portion 5c1 which strengthens the force of engaging with the case, and an engaging-force-decreased portion 5c2 which weakens the force of engaging with the case; and in response to an increase in internal pressure in the extinction chamber due to arcing gas generation, the engaging-force-decreased portion establishes disengagement of the case and provides a gap 27, formed with the case, for linking the extinction chamber to external air, and the engaging-force-increased portion maintains engagement with the case.

摘要： First fitting portions (9a and 9b) and second fitting portions (9c and 9d) are provided in a hook shape on the bottom (3a) of a housing so as to face each other. The first fitting portions are fitted to one rail edge (2a) of a rail (2) in the width direction and the second fitting portions are fitted to the other rail edge (2b) of the rail. A linear spring (10) that is bent in a mountain shape is provided on the bottom of the housing. The linear spring comes into contact with the end surface of the one rail edge to which the first fitting portions are fitted and is elastically deformed such that the inclination angle of the maintain is reduced. The urging force of the linear spring is applied to the rail such that the other rail edge is pressed by the second fitting portions.
