A sliding makeup implement, comprising: a case; a rod-shaped core used for makeup and capable of being advanced and retracted from the case when being used; a pair of case members (12, 13) that are obtained by dividing the case into two in a protruding direction of the rod-shaped core, the case members (12, 13) being slidably combined with one another; sliding grooves (18, 19) that are respectively formed in inner surfaces of the case members (12, 13) for arranging the rod-shaped core so that the core is capable of being advanced and retracted in an axial direction thereof; a core holder that is movable along the sliding grooves (18, 19) and holds the core at a base end thereof; and coupling means for pushing out the core by means of one case member and for bringing the one case member and the core into a coupled state when returning the pushed-out core to its original position, and for bringing the one case member and the core into an uncoupled state when leaving the core at the pushed-out position; wherein the coupling means includes: a first coupling hole that is formed in the core holder in a direction intersecting the axial direction of the core; a second coupling hole that is formed in the one of the case member and is located at a position where the second coupling hole is aligned with the first coupling hole when the core holder is located deep in the sliding grooves (18, 19); and a coupling pin that is movably provided inside the first and second coupling holes (21, 22), wherein the dimension of the coupling pin is set to be shorter than the length of the first coupling hole and longer than the length of the second coupling hole. a case; a rod-shaped core used for makeup and capable of being advanced and retracted from the case when being used; a pair of case members (12, 13) that are obtained by dividing the case into two in a protruding direction of the rod-shaped core, the case members (12, 13) being slidably combined with one another; sliding grooves (18, 19) that are respectively formed in inner surfaces of the case members (12, 13) for arranging the rod-shaped core so that the core is capable of being advanced and retracted in an axial direction thereof; a core holder that is movable along the sliding grooves (18, 19) and holds the core at a base end thereof; and coupling means for pushing out the core by means of one case member and for bringing the one case member and the core into a coupled state when returning the pushed-out core to its original position, and for bringing the one case member and the core into an uncoupled state when leaving the core at the pushed-out position; wherein the coupling means includes: a first coupling hole that is formed in the core holder in a direction intersecting the axial direction of the core; a second coupling hole that is formed in the one of the case member and is located at a position where the second coupling hole is aligned with the first coupling hole when the core holder is located deep in the sliding grooves (18, 19); and a coupling pin that is movably provided inside the first and second coupling holes (21, 22), a first coupling hole that is formed in the core holder in a direction intersecting the axial direction of the core; a second coupling hole that is formed in the one of the case member and is located at a position where the second coupling hole is aligned with the first coupling hole when the core holder is located deep in the sliding grooves (18, 19); and a coupling pin that is movably provided inside the first and second coupling holes (21, 22), wherein the dimension of the coupling pin is set to be shorter than the length of the first coupling hole and longer than the length of the second coupling hole.
