Abstract

A steering wheel includes: a boss part; a ring part that is located at an outer circumferential side of the boss part; a plurality of spoke parts that connect the boss part and the ring part; and a core including: a core boss part; a core ring part that is located at an outer circumferential side of the core boss part; and core spoke parts that connect the core boss part and the core ring part, wherein: the plurality of spoke parts include true spoke parts having the core spoke parts, and a pseudo spoke part that does not have the core spoke parts; and the pseudo spoke part is mounted on the core ring part, and includes a separate retaining member that retains a shape of the pseudo spoke part.

First claim

What is claimed is:

1. A steering wheel comprising:
a boss part;
a ring part that is located at an outer circumferential side of the boss part;
a plurality of spoke parts that connect the boss part and the ring part; and
a core comprising:
a core boss part;
a core ring part that is located at an outer circumferential side of the core boss part; and
core spoke parts that connect the core boss part and the core ring part, wherein:

the plurality of spoke parts include true spoke parts having the core spoke parts, and a pseudo spoke part that does not have the core spoke parts;
the pseudo spoke part is mounted on the core ring part, and includes a separate retaining member that retains a shape of the pseudo spoke part;
through-holes for mounting the retaining member are formed in the core ring part; and
the retaining member includes fitting parts fitted into the through-holes.

2. The steering wheel according to claim 1 , wherein
a plurality of mounting parts for mounting the retaining member are provided in the core ring part, and are spaced apart from one another.

3. The steering wheel according to claim 1 , wherein:
the retaining member is made of a first resin material;
the retaining member is covered by a covering member formed of a second resin material that is softer than the first resin material; and
the covering member is filled inside the through-holes.

4. The steering wheel according to claim 1 , wherein
the retaining member includes a pair of fitting parts fitted into the pair of through-holes.

5. The steering wheel according to claim 1 , wherein:
the retaining member is made of a first resin material;
the retaining member is covered by a covering member formed of a second resin material that is softer than the first resin material;
the pseudo spoke part includes a plurality of covers; and
the plurality of covers are engaged with the covering member.

6. A steering wheel comprising:
a boss part;
a ring part that is located at an outer circumferential side of the boss part;
a plurality of spoke parts that connect the boss part and the ring part; and
a core comprising:
a core boss part;
a core ring part that is located at an outer circumferential side of the core boss part; and
core spoke parts that connect the core boss part and the core ring part, wherein:

the plurality of spoke parts include true spoke parts having the core spoke parts, and a pseudo spoke part that does not have the core spoke parts;
the pseudo spoke part is mounted on the core ring part, and includes a separate retaining member that retains a shape of the pseudo spoke part;
the retaining member is made of a first resin material;
the retaining member is covered by a covering member formed of a second resin material that is softer than the first resin material;
the pseudo spoke part includes a plurality of covers;
the plurality of covers are engaged with the covering member; and
an inner surface of at least one of the plurality of covers is provided with:
a first engaging part that is engaged with a surface of the covering member which is opposite to the cover and restricts movement of the cover in a direction in which the cover is separated from the covering member; and
a second engaging part that is engaged with a surface of the covering member which faces the inner surface of the cover and restricts movement of the cover in a direction in which the cover approaches the covering member.

7. A steering wheel comprising:
a boss part;
a ring part that is located at an outer circumferential side of the boss part;
a plurality of spoke parts that connect the boss part and the ring part; and
a core comprising:
a core boss part;
a core ring part that is located at an outer circumferential side of the core boss part; and
core spoke parts that connect the core boss part and the core ring part, wherein:

the plurality of spoke parts include true spoke parts having the core spoke parts, and a pseudo spoke part that does not have the core spoke parts;
the pseudo spoke part is mounted on the core ring part, and includes a separate retaining member that retains a shape of the pseudo spoke part;
the retaining member is made of a first resin material;
the retaining member is covered by a covering member formed of a second resin material that is softer than the first resin material;
the pseudo spoke part includes a plurality of covers;
the plurality of covers are engaged with the covering member;
an insertion hole is formed in the retaining member;
a covering hole for covering an inner circumferential surface of the insertion hole is formed in covering member; and
a protrusion fitted into the covering hole is formed in the at least one of the plurality of covers.
