PURPOSE: To obtain a protector for a leg protecting a wider part of a knee without preventing movement of a knee joint by connecting an upper edge of a central part of a protector with an upper part of a protector having an edge to be overlapped without a gap and a lower edge of a central part with a lower part of a protector.

CONSTITUTION: A central part of a protector 1 is formed with a height (h) to cover a central part of a knee, and the upper edge 1a and the lower edge 1b of it are connected with an upper protector 2 and a lower protector 3 respectively. The central part of a protector 1 is formed to have a double-wall constitution, and an upper part of the inner wall 4 is given a stepped part 4a curved inward to the outer wall 5, in which a lower edge 2a of the upper protector 2 is slipped. In wearing the protector, a knee is pushed against the inner wall 4 leaving a gap between a knee and the lower edge 2a, which enable the upper protector 2 to move up and down freely. The lower edge 3b of the lower protector is connected with the central part of the protector 1 by a pin 8. The central part of the protector 1 protects a central part of a knee while the upper and the lower parts of the protector (2, 3) protect an upper and lower parts of a knee joint part, without preventing movement of a knee joint by altering the shape responding to a bending and extending movement of a knee.
