摘要： This invention concerns multi-point writing instruments of the kind wherein a pendulum effects selection and advance of the point carriers, one end of the pendulum being displaceably suspended in a pendulum control and support unit which is engageable with a plunger-like presser, there being a retraction spring for urging said unit towards said presser. In this invention, the said unit is a one-piece plastic member which has parts engageable with the presser, an integral spring guiding collar, and an integral resilient cage into which said one end of the pendulum is snap-fittable.
