The flower set has a rotatable stem. The gear assembly includes a third gear which has a circular recess and two matching holes. The third gear is formed with a stopper at a surface. The matching plug is retained in the circular recess and has a tube which is received by the central hole of the third gear and two matching holes. The first pinion has an end tube adaptable to be fixed in one of the matching holes, a sideward extending arm, and a hexagonal-shaped end tube which can be fixed in a hexagonal-shaped cavity of a head of the rotatable stem. The second pinion, which is meshed with the first pinion, includes an end tube fixable in the remaining matching holes of the matching plug, a sideward extending arm, and a round-shaped end tube which is retainable in an retaining cavity of the inner cover.

Abstract: A vehicle pressing cylinder, such as, for an automobile, installed between a master cylinder and the wheel cylinders thereof comprises a body defining three cylinders, e.g. a front cylinder, and right and left rear cylinders, the front cylinder having a larger bore than each of the right and left rear cylinders, a panel member covering one end of the body having passageways to concurrently direct brake fluid to each of the three body cylinders, and pistons reciprocably mounted in each of the three body cylinders.
