Abstract
To simplify the attachment of a cover member, an air intake duct 10 includes a duct body 12 having an air flow passage 14 communicating from an inlet port 12a to an outlet port 12b and a vent hole 28 communicating from the air flow passage 14 to the outside, an air permeable cover member 32, and a holding member 34 secured to extend along an outer inner circumferential surface or an inner circumferential surface of the duct body 12 and to hold a portion of the cover member 32 covering the vent hole at a location different from the vent hole 28. The holding member 34 is detachably attached to the duct body 12.
Claims13
An air intake duct comprising:
- a duct body comprising an air flow passage communicating from one end to another end of the duct body and a vent hole communicating from the air flow passage to an outside of the duct body;
- an air permeable cover member arranged to cover the vent hole;
- and
- a holding member extending along an outer circumferential surface or an inner circumferential surface of the duct body to secure the cover member to the duct body,
- wherein the holding member holds a portion of the cover member at a location different from the vent hole of the duct body,
- wherein an opening portion is provided in the holding member at a location corresponding to the vent hole of the duct body,
- wherein the holding member comprises a pair of holding portions opposed to each other across the opening portion,
- wherein the pair of holding portions presses the cover member against the duct body such that a tension is applied to the cover member,
- wherein the duct body is formed with a pair of holding receiving portions at locations corresponding to the pair of holding portions, and
- wherein, with regard to each of the holding portions and a corresponding one of the holding receiving portions, one of the holding portion and the holding receiving portion protrudes toward the other of the holding portion and the holding receiving portion such that the one of the holding portion and the holding receiving portion is inserted into the other of the holding portion and the holding receiving portion to hold the cover member between the holding portion and the holding receiving portion.

- wherein an opening portion is provided in the holding member at a location corresponding to the vent hole of the duct body,
- wherein a first ring-shaped protrusion is provided on an outer periphery of the opening portion of the holding member,
- wherein a second ring-shaped protrusion corresponding to the first ring shaped protrusion is provided on an outer periphery of the vent hole of the duct body,
- wherein the first ring-shaped protrusion is arranged to surround the second ring-shaped protrusion, and
- wherein the first ring-shaped protrusion and the second ring-shaped protrusion hold the cover member between a radially inner side wall of the first ring-shaped protrusion and a radially outer side wall of the second ring-shaped protrusion and apply a tension to the cover member.
