楽器の鍵装置。[Claims for Utility Model Registration] 1. A key device in which a key is swingable using its rear end as a fulcrum, a first lever that is pivotable by being pushed by the front of the fulcrum of the key, and a rear end of the key. 1. A key device for an electronic musical instrument, comprising: a second lever having a large moment of inertia that is rotatably supported on a shaft; the first lever and the second lever are connected by a link mechanism. 2. In a key device in which the key is swingable with its rear end as a fulcrum, there is a first lever that can be freely rotated by being pushed by the front part of the fulcrum of the key, and a lever that can be freely rotated by being pushed by the first lever. a second lever with a large moment of inertia, and the first lever has a rotation amount of the point of action of the first lever and the second lever that is larger than the amount of rotation of the point of action between the key and the first lever when the key is pressed. A key device for an electronic musical instrument characterized by having a lever ratio such that the amount of rotation of the key is small.
