A chassis cover supporting apparatus includes a chassis having a plurality of chassis sides and including a cover support receiving member positioned between the chassis sides. The siloxane copolymer provides good adhesion, freedom from water absorption, and yet can be reworked either in the field or during recycling of the solar cell components. The fuel composition preferably contains from 3 to 6% by weight of C1-C4 alkyl ester, calculated on the basis of the total weight of the composition. The driving component drives the food processing component to rotate relative to the container through the transmission mechanism.
