[The problem that the idea aims to solve]

Among the methods described in the prior art, when attaching a handle using a support metal fitting, it is necessary to pivotally support the support metal fittings at the front and rear parts of the handle, respectively, and then screw the support metal fittings to the kettle body. Therefore, there is a problem in that it takes time to attach the handle, and when installing the handle by locking the tip of the handle to the locking piece and screwing the rear end to the kettle body, it is difficult to attach the handle. Since the rear end of the kettle is screwed directly to the kettle body, the attachment part is repeatedly subjected to shocks during use, causing the attachment part to loosen and cause water to leak easily.

Furthermore, when attaching the one-handed handle, it is difficult to provide a locking portion on the kettle body, and it is also troublesome to attach the handle to the locking portion.

The present invention was developed in view of the problems of the prior art, and its purpose is to provide a handle that can be easily and securely attached, and that also has a good appearance. The aim is to provide equipment.

The spout lid 8 is supported in the front opening chamber 3 of the handle front column 2A so as to be swingable to open and close, and the operation button 9 of the spout lid 8 is inserted into the upper opening chamber 4 of the front column 2A. The spout lid 8 is provided with an arm 8a to be inserted into the front mouth chamber 3, and this arm 8
a is swingably supported, and a cam 18 is attached to the butt part of the arm 8a.
The operation button 9 has a push part 9a that is wider than the opening width of the upper opening chamber 4 and circumscribes the outside of the handle 2, and a leg part 9b that hangs down toward the upper opening chamber 4. The guide groove 1 of the upper spout chamber 4 is located between the spout lid cams 18.
A lever 15 that slides along the handle 2 is connected, and the lever 15 makes it impossible to separate, while also allowing the handle to slide back and forth along the outside of the handle 2. Further, the rear pillar 2B of the handle 2 has a downward opening 5 that is slightly larger than the stopper 7 at its lower end, and has a protrusion 5a inside thereof that engages with the claw 7c of the stopper 7. By locking with the stopper 7, the front column 2A is made unremovable. When attaching the handle 2 to the kettle body 1, attach the cap nut 6 and the stopper 7 to the kettle body 1 in advance, support one end of the lever 15 on the cam 18 of the spout lid 8, and first attach the handle front column 2A. The seat wall 3a is connected to the cap nut body 6a exposed from the kettle body 1.
Then, the rear post 2B is lowered toward the stopper 7, and the downward opening 5 of the rear post 2B is inserted into the stopper 7, and the claw 7c of the metal fitting tongue piece 7b and the downward opening protrusion The locking of the portion 5a makes it impossible to separate, and the front column seat wall 3a fitted into the nut body 6a is attached to the front column 2A.
