Abstract

In a disk wheel, a metal insert member is embedded in a resinous bolt-fastening part having a bolt hole. The insert member includes: an opposing surface which is opposed to a resin member of the bolt-fastening part; a bonding area a bonded to the resin member within the opposing surface; and a non-bonding area within the opposing surface. The non-bonding area is not bonded to the resin member, but extends from the bonding area so as to receive a load generated when the resin member deforms. It is thereby possible to provide a technique to effectively suppress the influence of residual stress remained after molding of the resin member of the bolt-fastening part, and to ensure the strength required for the bolt-fastening part.

First claim

The invention claimed is:

1. A disk wheel comprising a metal insert member embedded in a resinous bolt-fastening part having a bolt hole, wherein
the metal insert member includes:
an opposing surface which is opposed to a resin member of the resinous bolt-fastening part;
a bonding area which is bonded to the resin member of the resinous bolt-fastening part within the opposing surface; and
a non-bonding area which extends from the bonding area and is opposed to the resin member of the resinous bolt fastening part across a predetermined gap without being bonded to the resin member of the resinous bolt-fastening part so as to contact the resin member and receive a load caused by deformation of the resin member.

2. The disk wheel according to claim 1 , wherein
the disk wheel includes a plurality of the resinous bolt-fastening parts having a corresponding plurality of the bolt holes, and a plurality of the metal insert members,
the bolt holes are annularly arranged in a circumferential direction of the disk wheel, and each of the metal insert members is individually allocated to a corresponding one of the bolt-fastening parts.

3. The disk wheel according to claim 2 , further comprising a cylindrical rim, a discoidal disk jointed to the cylindrical rim, and a hub part which has the bolt holes and is mountable to an axle hub, and wherein fastening bolts of the axle hub are insertable through each of the bolt holes.

4. The disk wheel according to claim 3 , wherein
the discoidal disk comprises a plurality of spoke parts extending radially from the hub part; and
the metal insert members allocated to the respective bolt holes are arranged from a hollow part of the hub part to a hollow part of the respective spoke parts, and comprise through holes which are formed in an area of the metal insert members arranged in the hollow part of the hub part so as to form a part of the bolt holes.

5. The disk wheel according to claim 1 , further comprising
a cylindrical rim, a discoidal disk which is formed separately from the cylindrical rim, a peripheral part of the discoidal disk having a plurality of rim bolt holes, and a plurality of rim fastening bolts for fastening the cylindrical rim and the discoidal disk to each other are inserted through the rim bolt holes.

6. The disk wheel according to claim 2 , further comprising
a cylindrical rim, a discoidal disk which is formed separately from the cylindrical rim, a peripheral part of the discoidal disk having a plurality of rim bolt holes, and a plurality of rim fastening bolts for fastening the cylindrical rim and the discoidal disk to each other are inserted through the rim bolt holes.
