Abstract
A hammer device for an electronic keyboard instrument, enabling prevention of grease or the like from adhering to an actuator portion during mounting of the hammer, to thereby enable speedy hammer mounting work and improve the work efficiency. The hammer device includes a hammer support and hammers arranged side by side in a left-right direction and each pivotally supported by the hammer support to pivotally move in accordance with depression of an associated key. When mounting the hammer to the hammer support, before a shaft hole is engaged with a fulcrum shaft portion, left and right protrusions of the hammer are brought into abutment with respective left and right stopper walls provided close to the respective left and right ends of the fulcrum shaft portion, to thereby prevent the actuator portion from being brought into contact with the fulcrum shaft portion.
