Abstract
In the linear motor 1, which is provided with a pipe shaped member 11, a stator 10 including the pipe shaped member 11 and a plurality of magnets 12, both being accommodated in the stator 10 in such a manner that the plurality of magnets 12 are aligned in a line in the pipe shaped member 11 and same magnetic poles of magnets, being adjacent to each other and included in the plurality of magnets 12, oppose to each other, and a moving part 20 movably disposed on a circumferential surface of the pipe shaped member 11 in an opposing state, the pipe shaped member 11 is provided with a stopper structure 30 disposed at an end portion of the pipe shaped member 11 so as to prevent the plurality of magnets 12 from dropping out of the pipe shaped member 11. Accordingly, it is possible to simply and securely fasten the plurality of magnets 12 into stator 10 without occurring dropouts of the plurality of magnets 12 from the pipe shaped member 11, and without generating any backlash between them.
