Abstract
Disclosed is a coupling member that enables a joint between a wooden member and a mating member to absorb vibration energy, and a method for producing the same and a joint structure using the same. The metal coupling member is embedded in the wooden member. The wooden member is connected with a mating member by the coupling member. The coupling member includes a metal rod-like main body portion to be embedded in the wooden member, and an inner rod portion protruding from the main body portion. The inner rod portion axially extends from a protruding portion thereof to a predetermined depth in the main body portion, has a periphery separated from the main body portion to allow axial displacement of the inner rod portion relative to the main body portion, and is integrally connected to the main body portion at the deepest part thereof.
