ことを特徴とする電子鍵盤楽器のアクシヨン機構
。[Claims for Utility Model Registration] A pressing protrusion vertically installed on the lower surface of a key that is rotatably mounted on the keyboard chassis in the vertical direction; and a pressing protrusion on the keyboard chassis at a position opposite to the pressing protrusion. The key is supported for rotational displacement under the action of the key, and is in engagement contact with the pressing protrusion at an initial stage of key depression, and disengages from the pressing protrusion after the middle stage of key depression. In the action mechanism of an electronic keyboard instrument, the action mechanism of an electronic keyboard instrument includes an arm-shaped resistance member having an action part that comes into contact with the member and a weight that applies an appropriate inertia force to itself in the initial stage of key depression. A support for rotatably supporting the resistance member is provided on the top, and a circular pivot shaft is provided on one of the support and the resistance member, and the other is provided with a circular pivot shaft in a direction orthogonal to the axis. A circular pivot hole is provided that has a groove that can be inserted from the groove and that fits with the outer periphery of the pivot shaft, and the pivot shaft is inserted into the pivot hole through the groove and fitted. An action mechanism for an electronic keyboard instrument, characterized in that the resistance member is coupled to the support body.
