1. An embroidery frame comprising:
a base frame including a magnetic body;
a presser member configured to press a sewing object disposed between the presser member and the base frame toward the base frame, using a magnetic force, the presser member including:
a main body portion including an opposing surface facing the base frame and a magnet; and
a lever being provided with:
a support portion being rotatably supported on the main body portion to rotate around a rotational center;
a point of application portion provided on one end side of the lever in a lengthwise direction of the lever with respect to the rotational center, the lengthwise direction intersecting an extending direction of the rotational center, the point of application portion being pivotable to a stand-by position and an application position when the presser member is disposed on the base frame, the stand-by position being a position where the point of application portion is on a first side, in a orthogonal direction orthogonal to the opposing surface, separated further from the base frame than the opposing surface, the application position being a position where the point of application portion is on a second side, in the orthogonal direction, closer to the base frame than in the stand-by position; and
an operation portion provided on another end side of the lever with respect to the rotational center, the other end side being the opposite side from the one end side in the lengthwise direction of the lever, the operation portion moving the point of application portion from the stand-by position to the application position in accordance with the operation portion being operated to the first side in a state where the presser member is disposed on the base frame, to move at least a part of the main body portion to the first side in resistance to a magnetic force of the magnet, when the lever is in the stand-by position the opposing surface faces the base frame, and when the lever is in the application position the opposing surface faces the base frame; and
an opposing frame in which a hole is formed, the opposing frame facing the base frame, wherein
in an arrangement state where the sewing object is disposed between the base frame and the presser member, at least a part of the main body portion of the presser member being inserted into the hole of the opposing frame, the presser member presses the sewing object toward the base frame using the magnetic force, and
in the arrangement state, the point of application portion faces the opposing frame, and, in accordance with the operation portion being operated to the first side, comes into contact with the opposing frame and moves the main body portion to the first side.
