摘要： Provided is a handle structure for a bi-fold door that makes it: easy to find a handle; understand the direction in which fingers are to be inserted at a glance; and intuitively understand that the handle is to be pulled. The handle structure is provided with handles (40) and finger insertion recesses (42) disposed on each of first and second doors (22, 24). Each handle (40) is provided with a finger-hook plate piece (44) that extends vertically while protruding from the vicinity of one end faces (2202, 2402) on an outer surface (26A), where first and second doors (22, 24) are bendably joined, toward other end faces (2204, 2404). The finger insertion recesses (42) are formed on the outer surfaces (26A) of the first and second doors (22, 24) in such a manner as to face the finger-hook plate pieces (44), and are formed in dimensions that enable fingers to be hooked on inner surfaces (4404A) of the handles (40). The handles (40) and the finger insertion recesses (42) are formed in a bilaterally symmetrical shape with the end faces (2202, 2402), which face each other, of the doors (22, 24) in the center.
