The structure is such that when rotating the faucet member, a long pipe is rotated integrally. Therefore, the pipe is kinked and a relatively large rotational force is required, so Unreasonable force is applied to the joint between the tap and the faucet member.

[0003]   Furthermore, the sliding contact surface of the hollow support cylinder and the pipe is common in the vertical and rotational directions of the pipe. Since it is a sliding part, there is a problem that it wears quickly and loosens early.  .

[0004]   Also, pass the flexible tube from the water supply source through the pipe to the tip of the faucet member. In the case of the type that allows the faucet member to move to the original position by the reaction force of the tube when the faucet member is rotated. There is also a problem that it tends to return in the direction of, and the desired turning position cannot be maintained.

[0005]   Therefore, the first object of the present invention is to divide the vertical sliding part of the pipe and the rotating part of the faucet member. By separating and making it independent, excessive force is applied to the faucet member and the pipe when the faucet member turns. The upper and lower sliding parts and the swiveling part can maintain their functions for a long time. The purpose is to provide a curran device.

[0006]   The second object of the present invention is to counter the reaction force of the flexible tube built in the pipe. Provided is the above-described curran device capable of holding the faucet member at a desired turning position. And in.

[0007]   A third object of the present invention is to fix the position where the pipe is pulled out with respect to the hollow support cylinder. The tightening action of the seal member that can adjust the pressing force can be maintained at any height. It is to provide a curran device.

[0008]

[Effect of device]

  Since the vertical drive section and the rotary slide section are separated and independent in the curr device of the present invention, The pipe is not twisted, and excessive force is applied to the connection part between the pipe and the faucet member during rotation. No   Furthermore, both sliding parts are limited to either the vertical direction or the rotating direction, so wear resistance is outstanding. The braking function is maintained for a long period of time.

[0030]   Since the present invention is equipped with a braking mechanism that opposes the return reaction force of the tube, the faucet member Can be securely held at the desired rotation position, and especially when the faucet part is rotated. When configuring a rotary braking mechanism using a protruding member that regulates the angle, use only one member. It is extremely rational because it can be used for multiple purposes.   In addition, the frictional resistance necessary for vertical braking and the frictional resistance to oppose the tube reaction force. Although the resistance is not always the same, since the vertical sliding part and the rotating part are separated in the present invention, There is an advantage that a braking force suitable for each sliding portion can be set separately.
