PROBLEM TO BE SOLVED: To provide a hammer device of a keyboard instrument capable of preventing noise from being generated while securing the smooth rotation of a hammer, and reducing manufacturing costs.SOLUTION: A hammer device of a keyboard instrument imparts touch weight by rotation of a hammer 4 in association with a pushed key, and a chassis has a plurality of partition parts 50 provided among a plurality of laterally neighboring hammers 4, respectively. Each of the plurality of hammers 4 is composed of a molding of synthetic resin, and has a hammer main body 31 rotationally supported by the chassis via a support point 15a of a front half part and a weight 32 fixed to a rear half part of the hammer main body 31. The left and right side surfaces of the hammer main body 31 are provided with left and right counter protruding parts 39, 39 respectively which face each other via a predetermined gap in a partition part 50 of the chassis. |
