    CPC classification number: G10C3/26

    Abstract: A pedal unit according to an embodiment includes a first foot lever, a shaft serving as a center of rotation of the first foot lever, and a bearing paired with the shaft. The shaft or the bearing includes a first member arranged on at least a portion of surfaces in contact with each other, and a second member formed of a material different from the first member and supporting the first member from a side opposite the surfaces. The surfaces are included in an inner area of a width of the first foot lever when the first foot lever is viewed perpendicular to the shaft. The first member and the second member are fixed in a sliding direction of the shaft and the bearing.

    CPC classification number: G10C3/125

    Abstract: A key includes upper, front and side walls each having a flat shape, and a downwardly-opening space. The key includes a first part (e.g., the upper and front walls) normally visible from outside with the key assembled to the keyboard musical instrument; and a second part (e.g., the side walls) normally invisible from outside with the key assembled to the keyboard musical instrument. In molding, a first molding process is performed where resin is poured into a first mold to mold one of the part normally visible from outside and the part normally invisible from outside, and then a second molding process is performed where the one part molded by the first molding process is inserted into a second mold and resin is poured into the second mold so that the other of the parts is molded and thus the upper wall, front wall and side walls are insert-molded.

    Abstract: A keyboard device includes plural white and black keys 11w, 11b that rock according to a key depression/release operation. Positions of key support portions 13w, 13b supporting the plural white and black keys 11b, 11w in the longitudinal direction are set to be different from one another. The keyboard device also includes hammers 16w, 16b that rock with the rocking movement of the plural white and black keys 11w, 11b. The plural white and black keys 11w, 11b include drive units 11w1, 11b1 that drive the hammers 16w, 16b. The drive units 11w1, 11b1 and the pivot centers of the hammers are located on the same straight line extending in the lateral direction. An upper-limit stopper 21 and a lower-limit stopper 20, which restrict the rocking movement of the hammers 16w, 16b, are provided to extend in the lateral direction.
