A foldable consumer product, such as book or card, has a plurality of pages and a detachable toy, mask or other interactive amusement device attached to at least one of the pages. In the preferred embodiment, the concentration of the non-alcohol solvent in the concentrate is between about 75% and 85% by weight of the formulation. Further, the surface of the antistatic layer has a concavoconvex shape, and the height of convexes in the antistatic layer are not less than 40 nm and not more than 300 nm. or above, a solubility parameter of the polymer is 19. The driving circuit can produce driving waveforms that do not need to stay at ground potential. Further, a clutch drum is extended so as to be used in common by the second and third clutches, the second clutch is engaged and disengaged from the axial front side by a second piston of a second oil pressure actuator, and the third clutch is engaged and disengaged from the axial rear side by a third piston of a third oil pressure actuator.
