The present invention provides a structure which reduces an axial dimension of a front end-side portion of a worm shaft in a worm reducer including a pressing means for reducing backlash at a meshing portion. The worm reducer includes a coil spring (21) for pressing a rocking member (19), which is provided to be rockable about a rocking shaft (26), to one side (direction of arrow ²) in a rocking direction about the rocking shaft (26). The worm reducer further includes a guide member (18) configured such that, as the rocking member (19) rocks to the one side in the rocking direction about the rocking shaft (26), the worm shaft (5a) is moved in a meshing direction (direction from top to bottom in Figure) which is a direction in which the worm shaft (5a) comes close to a worm wheel and is pressed by the guide member (18) in the meshing direction through a front end-side bearing (8a) for supporting a front end of the worm shaft (5a).
