Abstract: Disclosed herein is a stepping motor for a slim optical disk drive (ODD). A casing which protects and covers a stator of a motor part is divided into two casing parts, and a casing part adjacent to an end of a rotating shaft has at least two insert holes in an end plate thereof. Thus, a support member which supports a center guide is fastened to the casing in such a way that the support member is inserted into the insert holes. The casing part adjacent to the end of the rotating shaft is integrally formed with the support member by insert molding. Therefore, the stepping motor of the present invention can satisfy the trend of a reduction in size and thickness.
