摘要

PURPOSE:To form a shaft support piece for a high scale which is narrow in the width without cracking by molding a base, a back plate, and many shaft support pieces out of synthetic resin in one body. CONSTITUTION:The base 28, the back plate 40 which is formed to the same length with a keyboard support plate and projects from the base 28, and many shaft support pieces 5 obtained by forming cut parts 29 as many as keys in a shaft support piece main body 5a, projecting from the base 28 in the same direction with and in parallel to the back plate 40, at the same intervals with arrangement intervals of many keys from the surface of the shaft support main body 5a to the substrate perpendicularly to the back plate 40 are molded out of the synthetic resin in one body. Consequently, the shaft support pieces 5 formed having a high scale and guide pieces of the keyboard are formed narrowly without cracking shaft support pieces 5 for the scale.
