Abstract
Each of the valve device and the shower device includes: a valve/shower device main body; a link lever pivotally held in the valve/shower device main body; a weight provided on the link lever; and a ball valve provided between the weight and a pivot axis of the link lever. When the valve/shower device main body is manually caused to move by shaking, swinging, turning, tilting, tapping, or like operation, a kinetic energy imposed on the weight causes the link lever to make a rotational movement relative to the valve/shower device main body, and then the rotational movement of the link lever displaces the ball valve to open or close a valve hole. The valve device and the shower device can significantly facilitate the valve-opening/closing operations, and do not require a special external member for hand- or finger-operation such as a button, a handle or a switch.
