ABSTRACT:
A clamp band has a pair of end portions formed in a loop-like shape around a cylindrical clamp member mounted on a member to be clamped and overlapped with each other and imparted a tangential clamping force and engaged with each other to clamp the clamp member to the member to be clamped. The first end portion which is the outer side during overlapping is formed with a first projection projectedly provided radially inwardly and a first clamping force imparting portion to which a clamping force is imparted during clamping, and the second end portion which is the inner side during overlapping is formed with a second projection projectedly provided radially outwardly and engaged with the first projection and a second clamping force imparting portion which is located more adjacent to the side opposite to the fore end of the second end portion than the second projection and to which a clamping force is imparted during clamping, and during clamping, a tangential clamping force is imparted to the first and second clamping force imparting portions to increase the amount of overlap, and the first and second projections are brought into engagement with each other to support a circumferential force, thereby clamping the clamp member to the member to be clamped.
