To provide a valve device having a locking mechanism which can easily be operated even by one hand.
This valve device is equipped with a valve frame body 10, a valve body 20, and a lever 30. In this case, the valve frame body 10 is attached to the periphery of a valve attaching hole 3 which is provided on a sealable bag body 2. The valve frame body 10 has an air passage hole 13 which takes out/puts in air to the inside and the outside of the bag body 2, and at the same time, has a valve body receiving surface 14 around the air passage hole 13. The valve body 20 is provided in such a manner that the valve body 20 can come into contact with/separated from the receiving surface 14. The lever 30 has a cam section 31 on one end side. On the cam section 31, a larger radius section 31a which places the valve body 20 with a valve closed by pressing the valve body 20 to the receiving surface 14, and a smaller radius section 31b which places the valve body 20 under a valve opening allowable state by separating from the valve body 20 are formed. Then, the cam section 31 is supported by the valve frame body 10 in a manner to turn within a desired angular range accompanying the rising/lying of the other end side. Under the valve opening allowable state, the valve body 20 separates from the receiving surface 14 by a suction from the outside of the valve frame body 10, and a valve opened state is presented.
