A drive module includes a drive unit having a cylindrical supporting member, a driven member accommodated inside the supporting member, and a driving unit configured to reciprocally move the driven member along the axial direction of the supporting member. A top-covered cylindrical cover is attached to the drive unit and covers the drive unit. The cover includes a metallic exterior packaging member configured to cover at least an outer periphery of the drive unit to shield the drive unit from external electromagnetic fields, and a resin spacer attached to the exterior packaging member, the spacer having engaging portions engageable with the drive unit to achieve positioning of the cover. |
