摘要：
A moving coil type phono pickup cartridge in which a stylus unit is very accurately positioned in three dimensions with respect to a cartridge body to thereby closely align a moving coil unit in the stylus unit with a corresponding magnetic unit in the cartridge body. The stylus unit is formed with first through third resilient plates which project from a side of the stylus unit. The cartridge body is formed with corresponding first through third polished positioning surfaces having engagement recesses at the base portions thereof in which are engaged engagement projections formed at ends of the resilient plates. A tab formed on the stylus unit abuts an upper polished surface of the cartridge body.
