Abstract

A press molded product 1 that includes fitting portions 13 and 15 , which can be fitted to another component 3 , wherein the fitting portions include protruded portions 19 that can be contacted to the fitted other component 3 , and the portions 19 are molded by press working.

First claim

What is claimed is:

1. A press molded product comprising:
a fitting portion that can be fitted to another component; wherein
the fitting portion includes a protruded portion that can be contacted to the other component,
the fitting portion includes a concave groove formed along an inner circumferential surface of the press molded product and formed continuously for substantially a whole circumference of the press molded product,
the protruded portion protrudes into the concave groove of the fitting portion in an axial direction of the press molded product,
the fitting portion is formed in a circular shape in a plane perpendicular to the axial direction,
the press molded product is a single component, and
the protruded portion is molded by press working.

2. A press molded product according to claim 1 , wherein a plurality of protruded portions are provided at the fitting portion in a state where the plurality of protruded portions are spaced apart.

3. A press molded product according to claim 2 , wherein the plurality of protruded portions are provided around an axis of the fitting portion in a state where the plurality of protruded portions are uniformly spaced at a predefined angle.

4. A press molded product according to claim 3 , wherein the predefined angle is 90 degrees, and four protruded portions are provided.

5. A press molded product according to claim 2 , wherein the other component is formed in a ring shape, and the protruded portions are formed in a circular shape with respect to a ring-shaped portion of the other component.

6. A press molded product according to claim 1 , wherein the fitting portion includes a fitting-guiding tapered surface that guides the other component in a direction where the other component is fitted to the fitting portion.

7. A press molded product according to claim 1 , wherein the fitting portion includes a fitting-holding tapered surface that applies drag, which prevents the other component from being separated from the fitting portion, to the other component.

8. A stopper for an engine starter, comprising:
the press molded product according to claim 1 ; and
a snap ring that is mounted around an output shaft of a starting motor for starting an engine and fitted to the fitting portion of the press molded product so as to hold the press molded product at a predefined position in a axial direction of the output shaft; wherein
the press molded product is contacted to a pinion gear, which is mounted around the output shaft, for starting the engine so as to regulate a movement of the pinion gear in the shaft direction, and
the press molded product is a stopper main body.

9. A press molded product according to claim 1 , wherein
an axial direction length of an inner circumferential surface of the protruded portion is longer than an axial direction length of an inner circumferential surface of another portion of the fitting portion.
