PROBLEM TO BE SOLVED: To unnecessitate the addition of force from an outer part when a pair of engagement parts are detached by executing the engagement of a facing part in clothes or a bag through the use of a magnetic force work which occurs by means of permitting a current to flow in an electromagnet. SOLUTION: The engagement parts 1 have two parts constituted to be freely attachable/detachable and the parts A with the arranged electromagnet 2, a power source 3 and a control part 4 are connected by wiring 5. The power source 3 is turned on/off or its polarity is inverted by using a switch, for example, in the control part 4. A magnetic body 6 is arranged in the other parts A'. The magnetic body 6 is attracted by the magnetic force of the electromagnet 2 which is disposed in one parts A so that the parts perform duties as the engagement parts 1. In this case, the engagement is cancelled by only turning off the power source. Thus, an effect that the engagement of clothes or a bag and its cancelling work are easily executed is obtained in a disabled person or an aged person or the like who is extremely weak and hardly executes an accurate work.
