Abstract

An attachment holder for construction equipment includes a movable-side pin guidance surface configured to guide a movable-side coupling pin to a movable-side pin accommodation portion. The attachment holder also includes an excessive closure prevention portion configured to prevent a movable-side jaw from closing excessively with respect to a stationary-side jaw to enable the movable-side coupling pin to come into contact with the movable-side pin guidance surface, whether the movable-side coupling pin is of an attachment for the construction equipment that has a minimum pin-to-pin spacing or a maximum pin-to-pin spacing, in a case in which the movable-side coupling pin is to be accommodated in the movable-side pin accommodation portion by operating, for example, an arm of the construction machine so as to move the movable-side jaw closer to the movable-side coupling pin after a stationary-side coupling pin is accommodated in a stationary-side pin accommodation portion.
