To reduce an exposure range of a rotary mechanism around a shaft coupling, and reduce burden for installing a shaft coupling guard.
A shaft coupling guard comprises: a guard body having a cylindrical trunk part, and a side part on which a through hole through which a main shaft penetrates is formed; and two leg parts supporting the guard body on one end side. The guard body is constituted so that it can be separated into two, a guard body upper part and a guard body lower part. A first flat part crossing in a vertical direction is formed on the trunk part at the guard body lower part in an axial line direction on both sides sandwiching an axial line therebetween. A second flat part parallel to the first flat part, and a step part having a step in the vertical direction are formed on each one end side of the two leg parts in the axial line direction. While the first flat part is located on the second flat part and displacement of the guard body lower part in a horizontal direction is limited, the two leg parts support the guard body.
