<p>PROBLEM TO BE SOLVED: To obtain a fixing structure of a slit disk and slit boss of a slit encoder capable of preventing the loose mounting and center misalignment of the slit boss and the slit disk with decreased production stages. SOLUTION: This fixing structure of the slit disk 1 and slit boss 2 of the slit encoder is constituted to fix the slit disk 1 to the slit boss 2 by fitting the columnar part 2b of the slit boss 2 for connecting various kinds of motors for control into the center hole 1b of the slit disk 1. At this time, a hooking part 1c consisting of a hooking piece is formed toward the center at the peripheral edge of the center hole 1b of the slit disk 1 and the center hole 1b is formed to a non-circular shape. The sectional shape of the columnar part 1b of the slit boss 2 is formed to the shape of the center hole 1b and this hooking part 1c is bitten into the columnar part 2b, by which the slit disk 1 is fixed to the slit boss 2.</p> |
