An energy accumulator for switchgear to make engagement and disengagement in a power train with no need of specific parts highly accurate in construction. On energy accumulation in a closing spring (22), a primary toothed wheel (5) is turned by means of a driving motor (3) or human power through an output toothed wheel (16) and an intermediate toothed wheel (33). After completion of energy accumulation in the closing spring (22), the intermediate toothed wheel (33) is released from meshing with the primary toothed wheel (5) because of a circular area (34) with no tooth around a gear (B). On closing operation of the switchgear, though energy free of the closing spring (22) gets the primary toothed wheel (5) turning, the intermediate toothed wheel (33) is disconnected from the primary toothed wheel (5) because of s slot (35) to bear a turning shaft (25) of the intermediate toothed wheel (33). On energy accumulation again in the closing spring (22), the intermediate toothed wheel (33) is allowed to come in mesh with the primary toothed wheel (5) by means of the slot (35) to bear a turning shaft (25) of the intermediate toothed wheel (33).
