PROBLEM TO BE SOLVED: To realize a structure that fully increases rigidity and prevents a detected surface 19 from being damaged when a plurality of encoders 5b are superposed axially in a direct manner. SOLUTION: The axially dimensional size L<SB>23a</SB>of a cylindrical part 23a for non-engaging part which composes the mandrel 15b of the above encoder 5b is made similarly as a magnitude more than the axially dimensional L<SB>18</SB>of a cylindrical part 18 for fastenings similarly (L<SB>23a</SB>≥L<SB>18</SB>). Then the nose of the cam edge of the above cylindrical part 23a for non-engaging part is wrapped with the part of a rubber (protection part 26) which composes an encoder body 16a. Such a constitution is adopted to solve the above subject. COPYRIGHT: (C)2007,JPO&INPIT |
