Abstract

PURPOSE:To make strength and rigidity high and obtain an arm of superior vibration characteristics by providing reinforced beams of honeycomb structure made of light metal radially in a pickup arm body of a pipe shape. CONSTITUTION:Reinforced beams 2 having honeycomb structure of light metal such as Al are radially provided in a pickup arm body 1 formed of metals, resins, glass, etc. Thereby, the strength and rigidity are made high and the arm of superior vibration characteristics is obtained.
