PURPOSE: To prevent a pipe-like body from slipping off or being damaged while gripped by constituting a claw for robot hand device for gripping and transferring a pipe-like body such as a winding roll by allowing elastic sheets which have particular dynamic and static friction coefficients with respect to the pipe-like body to stick to a claw base.
CONSTITUTION: A claw 2 which is installed on a robot hand device and grips a pipe-like body using a pair of opposing claws 2 has a claw base 31 constituting a valley part 31a which has an approximate V-shape. Elastic sheets 32 are allowed to stick to both inclined faces of the valley part 31a. In this case, the elastic sheet 32 has a dynamic friction coefficient (ASTM D1894-73) of 1.05 to 2.0 and a static friction coefficient (ASTM D1894-73) of 1.1 to 2.0 as well as a thickness of 8 to 5000μm. In addition, as the elastic sheet 32, silicone rubber, bridge silicone rubber, or flocculent low density polyethelene containing lubrication powders such as melamine or melaminecyanurate is used.
