PURPOSE:To achieve quick and sure operation even at greater shaking of a ship, by forming the main body of an operating part in a cylindrical shape possible for one-hand operation. CONSTITUTION:A main body 11 consists of a grip 11, a front main body 12 having an outer diameter slightly smaller than the grip 11, and a rear main body 13, and the outer diameter is made uniform by externally inserting an operating ring to the front main body 12 and the rear main body 13. At the external circumference of the bodies 12 and 13, a pair of ring packings 50 and 60 are respectively arranged and they seal the inside of a main body 1. The seal for both ends of the main body 1 is made by inserting a suitable seal member to the fitting part of a cover 49 and a partition 21. Further, the main body 1 is formed in a chevron shape as a whole for the easy operation of a knob 25 or an operation ring 5 with a finger by holding the grip 11. |
