To drive a fastener within a linear line which is at right angles with a base seat, ensure a adequate mounting of the base seat to a roof surface, and prevent a tear of the base seat, in an integrated fastener with which the base seat is mounted to the roof surface.
This fastener 16 is provided with a considerably large head and a plurality of legs extending from one side surface of the fastener 16, and holds a base seat on a roof surface by driving the legs so as to penetrate a comparatively thin base seat. A driving tool 10 comprises a driving mechanism, a fastener magazine, and a fastener feed mechanism. The fastener feed mechanism sequentially advances the fastener 16 from the fastener magazine, and drives the fastener 16 within a desired position of the roof surface. The fastener 16 is formed so as to obtain a uniform weight distribution around the fastener 16.
