    • PURPOSE:To make a tilt stopper into compactification in structure, by connecting a cranklike coupling part to a fulcrum shaft of a stop lever, and also connecting a spring to a crank part. CONSTITUTION:In the tilt stopper 17, straight-form fulcrum shafts 18L and 18R installed in each of symmetrical stop levers 16L and 16R are inserted into support hole parts 19L and 19R installed in a swivel bracket 14, and tip parts of both these fulcrum shafts 18L and 18R to be jutted with each other are joined together by a cranklike coupling part 20 which consists of collars 23L and 23R being fitted i these tip parts of these fulcrum shafts 18L and 18R and locked by locking pins 22L and 22R and a crank part 25 to be held between hole parts 24L and 24R installed in both these collars 23L and 23R. A tension spring 27 is installed interposingly between the spring receiving part 26 installed in the swivel bracket 14 and the crank part 25 of the cranklike coupling part 20.

    • PURPOSE:To prevent an impeller from inclination and its boss portion from intrusion of foreign matters by providing upper and lower ends of the boss portion of impeller with annular lips and making seal portions on inner periphery of both ends of the boss portion bear against the outer surface of a drive shaft and further ribs contact with resiliently the drive shaft. CONSTITUTION:Since annular lips 38, 39 are provided on upper and lower ends of a boss portion 32 of an impellet 30, foreign matters are blocked by these lips 38, 39 to reduce an amount of their intrusion into the interior of the boss portion 32. Also since seal portions 43, 44 formed on the inner peripheral surfaces of both ends 30a, 30b of boss portion 32 bear against the outer surface of a drive shaft 8, the interior of the boss portion 32 is prevented from the intrusion of foreign matters. Further, since ribs 45... are provided to resiliently contact with the drive shaft 8, the impellet 30 is not inclined with respect to the drive saft 8, and slide of inside surface of pump chamber on the lips 38, 39 and resilient contact between the seal portions 43, 44 and drive shaft 8 are ensured so that the interior of the both portion 32 can be prevented from the intrusion of foreign matters.
