When a rotating shaft member rotates, centrifugal force acts upon pressure members 152jk (j=1, . . ., J; k=1, . . . ,6) that are fixed to the rotating shaft member. When centrifugal force acts upon a pressure member 152jk, an other end portion of a second bar shaped member that is connected to a first bar shaped member shifts in the direction to approach a pressure transmission member, and a contact member that is connected to the other end portion of the second bar shaped member presses against the pressure transmission member. When the pressure transmission member 130 is pressed in this manner, this pressure is applied against a piezoelectric element of an individual power generation part 122jp that abuts in the radial direction against the pressure transmission member at the position of pressure. When pressure is applied to the piezoelectric element in this manner, the piezoelectric element continually and repeatedly generates a voltage.
