A presser foot device includes a wall portion, a pair of opposed portions, a pin, and an abutting portion. The wall portion extends in a first direction and a second direction intersecting the first direction. The pair of opposed portions extend in one direction of a third direction intersecting the first direction and the second direction from the wall portion, and face each other. The pin extends in the second direction between the pair of opposed portions, and engages with a groove provided in the presser foot holder. The abutting portion is provided with respect to the pin on one direction side of the first direction, and is provided on the one direction side of the third direction of an end surface in the one direction of the third direction, of the pair of opposed portions. The abutting portion abuts against the presser foot holder in the second direction.
