ROTATION-STOPPING DEVICE AND PROFILE-FOLLOWING APPARATUS

摘要

PROBLEM TO BE SOLVED: To make processing and fabrication simple and reduce manufacturing cost. SOLUTION: Right above an oscillating body 20, each of blocks 41-43 is connectedly located on an axis Z. A first protrusion 41a formed on the lower block 41 is engaged with a second groove 42a formed on the middle block 42 slidably. A second protrusion 43a formed on the upper block 43 is engaged with a second groove 42b formed on the middle block 42 slidably.
