PROBLEM TO BE SOLVED: To provide a projecting force transmission mechanism of a fuse striker wherein this is arranged so that the both projecting force transmission mechanism and a switch driving mechanism that simultaneously switches three-phase portion of the three-phase switch are operated by the projecting force of the striker without installing an energizing mechanism in order to increase transmitting force to the projecting force transmission mechanism. SOLUTION: This is provided with a first and a second projecting force transmission mechanisms 100Aa to 100Ac, 100B in which power fuses are constituted of three-phase portion, and which is operated so that the three-phase switch 51 is open circuited by utilizing the projecting force of the strikers 52a1 to 52c1 that are projected outward by fusion of the fuses 52a to 52c. The first projecting force transmission mechanism is constituted corresponding to the fuses so as to be operated by the projecting force. The second projecting force transmission mechanism is constituted to be operated according to either one of the operations of the first projecting force transmission mechanism. When the second projecting transmission is operated, a clearance g is installed at a normal state between the switch driving mechanism 69 that transmits the projecting force to make the three-phase portions of the three-phase switch open/close simultaneously and the second projecting force transmission mechanism.
