PROBLEM TO BE SOLVED: To provide a seedling transplanter capable of detecting the feeding amount of a seedling mat at any time. SOLUTION: A seedling placing table in which placing surfaces on which the seedling mat is placed in an inclined state is arranged side by side in the machine width direction according to the number of stripes, and a planting for scraping and transplanting seedlings from the lower end of the seedling mat In a seedling transplanter comprising a nail and a vertical feeding mechanism for feeding a seedling mat placed on the seedling mounting table downward, the seedling transplanting machine is provided so as to project upward from the back surface side of the mounting surface. Along with this, a rotary body that rotates in conjunction with the vertical feed of the seedling mat by the vertical feed mechanism is provided, and the rotary body is provided with a plurality of protrusions arranged radially with respect to the center of rotation, and the seedlings of the protrusions are provided. The surface on the side of contact with the mat has a shape curved to the upstream side in the rotation direction.
