Abstract

A keyboard device includes a plurality of transmission members (10) which are displaced in response to a depression operation on each of a plurality of keys (2) and a plurality of hammer members (11) each of which provides an action load to a depressed key (2) by performing a rotating motion in response to the displacement of a transmission member (10) corresponding to the depressed key (2). The weight of the transmission member (10) is set in accordance with the formation density of a plurality of ribs (22b, 45b) formed on a transmission body section (22, 45). Therefore, the weight of the transmission member (10) set in accordance with the formation density of the ribs (22b, 45b) can be provided to the key (2) as a static load. As a result of this structure, an initial load on a key (2) can be optimized, and a key depressing force on the key (2) at the time of key depression can be favorably transmitted to the hammer member (11).
