发明名称 Key for keyboard instrument
摘要 A key for a keyboard instrument, which makes it possible to easily attach a weight to a synthetic resin-made key body while securing a desired touch weight to be given during key depression, and can be manufactured at low costs. The key includes a pivotally movable key body made of a synthetic resin, extending in a front-rear direction, and having a recess open downward, and a weight made of a material whose main component has an elasticity, and attached to the key body in a state received in the recess. The recess has a locking portion formed at an opening edge portion in a manner projecting therefrom such that the locking portion allows the weight to be received into the recess while being elastically deformed when the weight is attached to the key body, and locks the received weight in a state prevented from falling out.
