Abstract

A clasp includes a first clasp member and a second clasp member that are separable. The first clasp member includes a first connecting portion to which a linear member is connected, and a first coupling portion that is formed with the first connecting portion. The second clasp member includes a second connecting portion to which the linear member is connected, a second body portion that is continuous from the second connecting portion, a second coupling portion that extends from the second body portion in a direction away from the second connecting portion, and that has a hook shape to be coupled to the first coupling portion, an opening-and-closing portion that is pivotally supported by the second body portion, and that includes an abutment portion, and which is brought into abutment against the second coupling portion, and a locking portion that maintains a state of the abutment of the opening-and-closing portion.

Dependent claims

A clasp for an accessory, the clasp comprising:

a first clasp member that is arranged at one end portion of a linear member of the accessory;
a second clasp member
that is arranged at another end portion of the linear member and
that is capable of being coupled to and separated from the first clasp member, the clasp further comprising:
the first clasp member includes
a first connecting portion to which the one end portion of the linear member is connected, and
a first coupling portion
that is formed integrally with the first connecting portion and
that is coupled to the second clasp member,
the first coupling portion includes an insertion hole portion that is provided to allow a part of the second clasp member to be inserted through the insertion hole portion, and
the second clasp member includes
a second connecting portion to which the other end portion of the linear member is connected,
a second body portion that is formed continuously from and integrally with the second connecting portion,
a second coupling portion
that extends from the second body portion in a direction away from the second connecting portion, and
that has a fish-hook shape to be coupled to the first coupling portion, an insertion-and-removal opening portion
that communicates with an inside space portion of the second coupling portion, and
that allows a part of the first coupling portion to pass through the insertion-and-removal opening portion,
an opening-and-closing portion
that is pivotally supported by the second body portion such that the insertion-and-removal opening portion is opened and closed, and
that includes an abutment portion
which has
a substantially L-shape or
a substantially circular-arc shape, and
which is brought into abutment against an outer peripheral surface of the second coupling portion,
a locking portion
that locks the opening-and-closing portion when the second coupling portion is brought into abutment against the opening-and-closing portion, and
that maintains a state of the abutment, and
a protruding piece portion
that protrudes from an outer peripheral surface of the abutment portion to an outside,
that is closer to the first clasp member than to the second connecting portion when the abutment portion has been held in abutment against the second coupling portion, and
that overlaps the first clasp member when the abutment portion has been held in abutment against the second coupling portion.
