Abstract: A keyboard instrument includes a plurality of key blocks, each including key main bodies, connecting sections, and a supporting section. Each key main body has a top surface that can be pressed by a user to play the keyboard instrument. Each connecting section extends from a key main body and deforms in response to pressing at the top surface of the key main body. The supporting section supports the key main bodies as one key block through the connecting sections. The key blocks are stacked at the supporting section in an instrument case so that a plurality of connecting sections of one key block and a plurality of connecting sections of another key block overlap each other. In at least one key block, each connecting section extends from a top surface side of the corresponding key main body.

Abstract: A keyboard apparatus is provided, which is provided with plural keys 2 disposed in parallel, plural transmission members 10 rotating in response to a key pressing operation on the plural keys, and plural hammer members 11 rotating in accordance with rotation of the transmission member to give an action load to the key. The weights of the transmission members together with the weights of the hammer members bring the plural keys to the initial positions and initial loads of the keys are adjusted by the weights of the hammer members. Even if the weight of the hammer member is changed, the initial load of the key can be adjusted based on the weight of the transmission member. Therefore, when the weights of the hammer members are changed, the initial loads of the keys can be kept constant on the high-pitched tone side and the low-pitched tone side.
