Abstract

The present invention relates to a fitting member ( 1 ) including an insertion portion ( 11 ) that fits a long member (Ia) therein and has a space through which the long member (Ia) is insertable, a movement restriction portion ( 14 ) that restricts movement that the long member (Ia) comes out of the insertion portion ( 11 ), the movement restriction portion ( 14 ) being capable of being scraped with a tool, and a guide portion ( 16 ) that guides the tool to the movement restriction portion ( 14 ) when the movement restriction portion ( 14 ) is scraped with the tool, the fitting member ( 1 ) including the movement restriction portion ( 14 ) that can be scraped with the tool to release the restriction of the movement that the long member (Ia) comes out of the insertion portion ( 11 ).

First claim

The invention claimed is:

1. A fitting member for fitting a long member therein, the fitting member comprising:
an insertion portion including a space through which the long member is insertable;
a movement restriction portion configured to restrict movement that the long member comes out of the insertion portion, the movement restriction portion being capable of being scraped with a tool; and
a guide portion configured to guide the tool to the movement restriction portion when the movement restriction portion is scraped with the tool, wherein
the restriction of the movement of the long member is released after the movement restriction portion is scraped with the tool,
the insertion portion, the movement restriction portion, and the guide portion are formed as one continuous slit, and
the one continuous slit extends in a direction perpendicular to an axis of the long member.

2. The fitting member according to claim 1 , wherein
the guide portion includes opposing tapered surfaces and is formed such that a space between the tapered surfaces is reduced toward the movement restriction portion.

3. The fitting member according to claim 2 , wherein
the insertion portion is a slit extending in a direction perpendicular to an axial direction of the long member,
the movement restriction portion is a projection protruding from the slit to reduce the width of the slit, and
the space width of a narrowed portion having the width of the slit reduced by the projection is smaller than the width of the long member.

4. The fitting member according to claim 1 , wherein
the insertion portion is a slit extending in a direction perpendicular to an axial direction of the long member,
the movement restriction portion is a projection protruding from the slit to reduce the width of the slit, and
the space width of a narrowed portion having the width of the slit reduced by the projection is smaller than the width of the long member.

5. A replacement unit for a long member to be fitted in a fitting member, comprising:
a fitting member including an insertion portion including a space through which the long member is insertable, a movement restriction portion configured to restrict movement of the long member from the insertion portion toward a direction perpendicular to an axial direction of the long member, the movement restriction portion being capable of being scraped with a tool, and a guide portion configured to guide the tool to the movement restriction portion when the movement restriction portion is scraped with the tool, the guide portion including tapered surfaces formed such that the tapered surfaces are opposed each other and a space between the tapered surfaces is reduced toward the movement restriction portion, the restriction of the movement of the long member being released after the movement restriction portion is scraped with the tool; and
the tool configured to scrape the movement restriction portion, wherein
the tool includes tapered surfaces, the thickness between the tapered surfaces being reduced toward a distal end of the tool, the tapered surfaces of the tool being configured to be guided by the tapered surfaces of the guide portion,
the insertion portion, the movement restriction portion, and the guide portion are formed as one continuous slit, and
the one continuous slit extends in a direction perpendicular to an axis of the long member.

6. The replacement unit for the long member according to claim 5 , wherein
the insertion portion is a slit extending in the direction perpendicular to the axial direction of the long member,
the movement restriction portion is a projection protruding from the slit to reduce the width of the slit,
the space width of a narrowed portion having the width of the slit reduced by the projection is smaller than the width of the long member, and
the width of the distal end of the tool is smaller than the space width of the narrowed portion.

7. The replacement unit for the long member according to claim 6 , wherein
the tool includes a distal end portion where the tapered surfaces are formed, and a proximal end portion, and
the width of the proximal end portion of the tool is larger than the width of a slit where the projection is not formed.

8. The replacement unit for the long member according to claim 5 , wherein
the tool includes a distal end portion where the tapered surfaces are formed, and a proximal end portion, and
the width of the proximal end portion of the tool is larger than the width of a slit where the projection is not formed.
