The driver 10 has a body 1 including a shaft 11 and a grip 12. The driver 10 includes an insulation tube 2 covering the shaft 11. The shaft 11 has, on the distal end, a blade edge 11a inserted into the engagement groove 71 of the head 7a to engage with it. The grip 12 is fixed with the proximal end of the shaft 11. The insulation tube 2 has a hollow holder 21 protruding from the distal end edge of the shaft 11 so as to be inserted with the head 7a of the screw 7 and elastically hold the outer periphery of the head 7a of the screw 7.
