Abstract
According to one embodiment, a hose clamp has a leaf spring body, a slit and a first knob piece at one end, and an insertion piece and a second knob piece at the other end. An interlocking piece is formed in the first knob piece, and an engaging holding part is formed in the second knob piece. When the hose clamp is viewed from the outside in the radial direction while the leaf spring body is in a free state of being compressed, the first knob piece and the second knob piece are extended outward in the width direction so as to be separated.
Claims9
A hose clamp comprising a leaf spring body that is bent to have an annular shape,
- wherein a one end portion of the leaf spring body comprises:
- a slit formed along a circumferential direction;
- and
- a first tab piece bent in a radial outer direction,
- wherein the other-end portion of the leaf spring body comprises:
- an insertion piece configured to be inserted into the slit and slidable in the circumferential direction in the slit;
- and
- a second tab piece bent in the radial outer direction from an end portion of the insertion piece and facing the first tab piece,
- wherein the leaf spring body is configured to be radially expanded from a free state where the leaf spring body is reduced in diameter, by making the first tab piece and the second tab piece approach each other against an elastic force of the leaf spring body,
- wherein the first tab piece comprises:
- an engaging piece that extends in the circumferential direction from the first tab piece toward the second tab piece, and comprises a locking portion that protrudes in a width direction of the leaf spring body, and is engageable with a surface of the second tab piece that is opposite to the surface facing the first tab piece,
- wherein the second tab piece comprises:
- an engagement holding portion that holds an engaged state when the locking portion of the engaging piece is engaged with the engagement holding portion, and is disposed on the surface of the second tab piece that is opposite to the surface facing the first tab piece, and
- wherein, when viewed from the radial outer direction in the free state where the leaf spring body is reduced in diameter, at least one of the first tab piece, the second tab piece and the engaging piece is bent at an angle inclined with respect to a direction perpendicular to a widthwise center line of the leaf spring body and extends outward in the width direction, so that a side surface of the engaging piece closer to the widthwise center line and a side surface of the second tab piece around the engagement holding portion closer to the widthwise center line are separated from each other.
