Guard device for a grinding wheel in a grinding machine
 A guard device for a grinding wheel in a grinding machine comprises a side guard plate pivotably mounted upon a guard body for covering one side face of the grinding wheel. A front cover member is slidably mounted upon the top portion of the guard body for covering the upper front portion of the grinding wheel. A latch member is mounted on the front cover member to be engaged with a saw-toothed member so as to restrict movement of the front cover member away from the periphery of the grinding wheel but to allow movement of the front cover member toward the periphery of the grinding wheel. A locking member is pivotably mounted on the top of the guard body to lock the side guard plate in a closed state. When the locking member is pivoted to be disengaged from the side guard plate, the saw-toothed member is also disengaged from the latch member.
