Abstract

PURPOSE:To contrive an improvement in workability and miniaturization and cost down of an equipment, by making a piezoelectric element into a brake medium. CONSTITUTION:A piezoelectric element 2 and a brake 4 are fixed to a shaft 1 and a rotating roller 6 is supported by the shaft 1 through a ball bearing. Although the rotating roller is rotatable always, the piezoelectric element 2 is expanded in the direction of an arrow by applying voltage to the piezoelectric element 2 and the rotating roller can be braked.

Description

【発明の詳細な説明】 本発明にブレーキ機構にかかり、とくに出力機器の制動
