Abstract
An adjust pin ( ) for connecting a plurality of blocks ( ) to each other to make up a wrist watch band ( ) is formed of a metal with a property having a superelastic region where a stress remains constant against variation in strain. The adjust pin ( ) is provided with a bent part ( ) for causing a bending stress in the superelastic region to act on the inner wall face of a connecting through-hole ( ) of a block ( ) in a state wherein the block ( ) is joined with an adjoining block ( ). When the adjust pin ( ) is inserted in the blocks ( ), and the bent part ( ) is positioned in the connecting through-hole ( ), the bent part ( ) provides a force acting on the inner wall of the connecting through-hole ( ) by the agency of the bending stress in the superelastic region, thereby securely holding the adjust pin ( ) by a spring force thereof.
