<P>PROBLEM TO BE SOLVED: To provide a motor along with a fixing structure of a circuit board, capable of realizing a sufficient durability even if a circuit board, a board surface of which faces the axial direction, is fixed in a tubular case by using an adhesive. <P>SOLUTION: Relating to an encoder 8 of a stepping motor, a circuit board 85 is, with board surfaces 85a and 85b facing a direction of motor axis line L, positioned by a first step part 806 on an output side L1 in the direction of motor axis line L, inside a metal encoder case 80, and is fixed by using an adhesive 60 provided on an anti-output side L2 in the direction of motor axial line. On an inner peripheral surface 802 of the encoder case 80, a second step part 807 is formed which faces the circuit board 85 side on the output side L1. The adhesive 60 is provided from at least a position contacting to the circuit board 85 to a position reaching the second step part 807 along the inner peripheral surface 802 of the encoder case 80. <P>COPYRIGHT: (C)2012,JPO&INPIT |
