Abstract: A fuel tank supporting structure is described which is effective to reliably fix a fuel tank without interfering with the layout of auxiliaries, such as a pump unit, a meter unit, and the like mounted on the fuel tank, and to ensure a sufficient volume of the fuel tank. The disclosed structure includes a subframe for supporting the fuel tank in an internal space having a pair of front and rear cross members, a pair of left and right side members, a pair of fuel tank supporting members disposed inside and below both the side members, and suspension arm supporting brackets located at a level higher than the fuel tank supporting members. The fuel tank placed on the fuel tank supporting members is fixed at its left and right opposite sides by a pair of left and right tank supporting bands which are connected at their front ends to the suspension arm supporting brackets and at its rear ends to the rear cross member.

Abstract: An optically active liquid crystal compound which is represented by the formula: ##STR1## wherein R.sub.1 and R.sub.2 each represents an alkyl or aralkyl group of 4-18 carbon atoms, R.sub.3 represents a haloalkyl group, X represents O, COO, OCO, CO or a single bond, Y represents COO, OCO, CH.sub.2 O or OCH.sub.2, Z represents COO or O, (A) represents a cyclic group shown by ##STR2## (B) represents a cyclic group shown by ##STR3## and l shows that the cyclic groups are substituted by at least one halogen atom.

Abstract: An object of the invention is to offer an locking mechanism for a tape reel in a magnetic tape cassette so that accidental disengagement and overlocking trouble can be prevented, wherein proper engagement and disengagement between a reel-locking lever and the tape reel is attained by arranging the sliding surface of the reel-locking lever at a predetermined position.
