In this conventional type, a closure as a rotating stopper inserted into the flow path of the Kotsuk body is transmitted to a pair of push buttons via a combination mechanism of a rack and a gear mechanism, and the operating shaft of the closure is The gears attached to the opening mesh with the racks provided on both the open and close push buttons.

In this case, when one push button for opening is pushed in, the closure is rotated to the fully open position by the meshing of the rack and the gear, and the push button for closing is projected. Conversely, when this push button for closing operation is pushed in, the closing element is rotated to a fully closed state, and the relationship between the protrusion and retraction of each push button is reversed.

However, this conventional device has a problem in that the operating mechanism section becomes large.

This is because separate push buttons are provided for opening and closing operations.

(Technical Problem) The present invention includes a rotating body 10 attached to a rotating plug 1 of the type that opens and closes a flow path by rotation,
A pair of sliding rods 21 and 22 are provided in parallel, facing each other with this rotating body 10 in between, and both positively interlocked with this rotating body 10, and the sliding rods 21 and 22 are individually pushed. In order to reduce the size of the operating mechanism in a device that opens and closes the flow path by rotating the rotary stopper 1, the sliding rods 21 and 22 can be pushed in separately by one operating section. This is the technical issue.
