Portable blower
Provided is a portable blower including a portable main body in which a pipe base portion of a blowout pipe is connected to an outlet port of a fan case, wherein, the fan case is formed of a fiber-reinforced resin of low specific gravity, the pipe base portion has a bent shape and is connected slidably to a pipe connecting portion of the outlet port, and a slide-contact-receiving member that is formed of a wear-resistant material is attached to the pipe connecting portion at a slide-contact point of the pipe base portion.
1. A portable blower comprising a portable main body in which a pipe base portion of a blowout pipe is connected to an outlet port of a fan case, wherein,
the fan case is formed of a carbon fiber-reinforced resin of low specific gravity,
the pipe base portion has a bent shape and is connected slidably to a pipe connecting portion of the outlet port,
a slide-contact-receiving member that is formed of a wear-resistant material is attached to the pipe connecting portion at a slide-contact point of the pipe base portion, and
the slide-contact-receiving member is configured to move as the pipe base portion slides with respect to the pipe connecting portion such that wearing of the pipe connecting portion is reduced.
2. The portable blower according to claim 1 , wherein
the pipe connecting portion is constituted of a pair of split bodies for clamping the pipe base portion,
a projecting portion projecting toward the inside of the pipe connecting portion is formed partially along a circumferential direction of the pipe base portion, the projecting portion being provided with a joining portion of the split bodies in the pipe connecting portion, and
the slide-contact-receiving member is attached to a section inside the pipe connecting portion excluding the projecting portion.
3. The portable blower according to claim 2 , wherein the slide-contact-receiving member is a pair of split members corresponding to the split bodies.
4. The portable blower according to claim 2 , wherein a fitting portion configured to be fitted to a fitting projection projecting outward along the circumferential direction of the pipe base portion is formed in the slide-contact-receiving member.
5. The portable blower according to claim 2 , wherein the slide-contact-receiving member comprises an engaging portion configured to engage with an end portion of the projecting portion.
6. The portable blower according to claim 2 , wherein
a base end portion of the pipe base portion is provided with a taper portion, an inner surface of which expands in diameter toward a base end thereof, and
a storing recess for storing the taper portion is provided inside the pipe connecting portion.
7. The portable blower according to claim 1 , wherein the slide-contact-receiving member is formed of the same material as the pipe base portion.
8. The portable blower according to claim 1 , wherein
a material of the fan case is carbon fiber reinforced polypropylene, and
a material of the slide-contact-receiving member is glass fiber reinforced polyamide.
9. The portable blower according to claim 1 , wherein the pipe connecting portion comprises a holding portion, and the holding portion comprises a detent projection configured to lock the slide-contact-receiving member.
