PROBLEM TO BE SOLVED: To provide a device that can perform interrow grooving work simultaneously, while performing the weeding of interrow spaces and hill spaces of the rice stubble, in the weeding work of a paddy, particularly in the weeding work during a mid-term and late term when rice stubble grows and weeds also grow, and the field ground is hardened to cause the weeding difficult.SOLUTION: A paddy weeding machine is characterized as follows: two or more weeding devices are juxtaposed to a traveling direction in the lateral direction of a frame connected left and right horizontally in a travelling frame body the weeding device front is inclined to form a sledge so that the tip of the traveling direction rises more than a ground bottom face a side plate part installed downward from a ground bottom face at a weeding device rear is formed so that the size in the height direction is shortened as going to the weeding device front the lower end front of the side plate part is joined and is formed substantially in a V-shape when viewed from the back elastic strip materials comprising rectangular rubber strips having two-fold creases outside are installed along overhang plate parts protruded out from the upper end of the side plate part and eight-shaped to the outward direction symmetrically toward the rear and outside tips of the elastic strip materials of adjacent weeding devices are disposed to come in contact with each other.
