Abstract: A motor-vehicle door latch has a housing, a fork pivotal on the housing between a bolt-retaining latched position and a bolt-releasing unlatched position, and a pawl pivotal on the housing between a holding position engaging the fork and retaining it in the latched position and a freeing position allowing the fork to move into the unlatched position. A wheel rotatable about an axis has a radially directed cam surface on which rides a projection on the pawl. A drive motor can rotate the wheel and thereby engage the surface with the projection to displace the pawl into its freeing position. A spring is braced between the pawl and the housing and urges the pawl into the holding position and the projection into engagement with the surface. Furthermore the wheel has a groove having a pair of ends, one radially directed flank formed by the cam surface, and an opposite radially directed flank forming another surface.
