PROBLEM TO BE SOLVED: To provide an automatic body leveling mechanism for horizontally correcting a seedling planting device of a walk type rice transplanter by a body inclination detected by an inclination detector, and an operator appropriately adjusts the inclination of the body. The challenge is to be able to correct it manually. SOLUTION: The seedling planting device 3 is attached to the rear part of the machine body 2 traveling on the left and right traveling wheels 10, 10 and the pendulum mechanism 45 detects the lateral inclination of the machine body 2, and the left and right traveling wheels 10, 10 are hydraulically controlled. In the walk-type rice transplanter that raises and lowers to keep the seedling planting device 3 horizontal, an interlocking wire 44 that is connected to the pendulum arm 37 of the pendulum mechanism 45 is provided, and the interlocking wire 44 is manually operated to provide the pendulum arm. A walking type rice transplanter in which 37 is moved to horizontally correct the inclination of the body 2 is used.
