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

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

2 . (canceled)

3 . The disk wheel according to claim 1 , wherein,
a plurality of said bolt holes are annularly arranged in a circumferential direction of said disk wheel, and each of said insert members is individually allocated to each of said resin members of said bolt-fastening part, each of said resin members corresponding to each of said bolt holes.

4 . The disk wheel according to claim 3 , comprising said disk wheel comprises a cylindrical rim, a discoidal disk jointed to said rim, and a hub part which has said bolt holes and is opposed to an axle hub within said disk, and wherein, a fastening bolt provided to said axle hub is inserted through each of said bolt hole.

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

6 . The disk wheel according to claim 1 , wherein,
said disk wheel comprises a cylindrical rim, a discoidal disk which is formed separately from said rim, and a peripheral part having said bolt holes within said disk, and a fastening bolt for fastening said rim and said disk to each other is inserted through each of said bolt holes.

7 . The disk wheel according to claim 3 , wherein,
said disk wheel comprises a cylindrical rim, a discoidal disk which is formed separately from said rim, and a peripheral part having said bolt holes within said disk, and a fastening bolt for fastening said rim and said disk to each other is inserted through each of said bolt holes.
