３．本実施形態に係る乗物シート用フレーム（特に、挿入部及び被挿入部）の特徴
挿入部１２の外周面及び被挿入部１３の内周面のうち少なくとも一方の周面１２Ａには、他方の周面１３Ａから離間してパイプ材１１の内外を連通させる隙間１６Ａを構成する第１連通部１４が設けられている。 3. 3. Features of the vehicle seat frame (particularly, the insertion portion and the inserted portion) according to the present embodiment The outer peripheral surface of the insertion portion 12 and the inner peripheral surface of the inserted portion 13 have at least one peripheral surface 12A on the other peripheral surface. A first communication portion 14 is provided so as to form a gap 16A that communicates the inside and outside of the pipe material 11 with a distance from the surface 13A.

つまり、本実施形態に係るフレーム本体５Ａでは、少なくとも第１隙間１６Ａを介してパイプ材１１の内外が連通しているので、パイプ材１１の内圧が過度に上昇してしまうことが抑制される。 That is, in the frame main body 5A according to the present embodiment, since the inside and outside of the pipe material 11 communicate with each other through at least the first gap 16A, it is possible to prevent the internal pressure of the pipe material 11 from increasing excessively.

第１隙間１６Ａを構成する第１連通部１４は、挿入部１２の円筒外周面から内方側に凹んだ部位にて構成されている。これにより、フレーム本体５Ａを製造する者は、挿入部１２及び第１連通部１４を容易に製造でき得る。 The first communication portion 14 constituting the first gap 16A is formed by a portion recessed inward from the outer peripheral surface of the cylinder of the insertion portion 12. As a result, a person who manufactures the frame body 5A can easily manufacture the insertion portion 12 and the first communication portion 14.

なお、第２隙間１６Ｂを構成する第２連通部１５も第１連通部１４と同様に、挿入部１２の円筒外周面から内方側に凹んだ部位にて構成されている。これにより、フレーム本体５Ａを製造する者は、挿入部１２及び第１連通部１４を容易に製造でき得る。 The second communication portion 15 forming the second gap 16B is also formed of a portion recessed inward from the outer peripheral surface of the cylinder of the insertion portion 12, similarly to the first communication portion 14. As a result, a person who manufactures the frame body 5A can easily manufacture the insertion portion 12 and the first communication portion 14.

第１連通部１４は、挿入部１２及び本体部１１Ｂに跨るように、挿入部１２と本体部１１Ｂとの境界を越えて当該本体部１１Ｂまで延びている。これにより、パイプ材１１の内圧が上昇した際に、パイプ材１１内の気体は、確実に外部に排出される。 The first communication portion 14 extends beyond the boundary between the insertion portion 12 and the main body portion 11B to the main body portion 11B so as to straddle the insertion portion 12 and the main body portion 11B. As a result, when the internal pressure of the pipe material 11 rises, the gas in the pipe material 11 is surely discharged to the outside.

なお、第２連通部１５も第１連通部１４と同様に、挿入部１２及び本体部１１Ｂに跨るように、挿入部１２と本体部１１Ｂとの境界を越えて当該本体部１１Ｂまで延びている。これにより、パイプ材１１の内圧が上昇した際に、パイプ材１１内の気体は、確実に外部に排出される。 Similar to the first communication portion 14, the second communication portion 15 also extends beyond the boundary between the insertion portion 12 and the main body portion 11B to the main body portion 11B so as to straddle the insertion portion 12 and the main body portion 11B. .. As a result, when the internal pressure of the pipe material 11 rises, the gas in the pipe material 11 is surely discharged to the outside.

第１連通部１４の延び方向本体部１１Ｂ側には、当該本体部１１Ｂに近づくほど幅方向寸法が拡大するテーパ部１４Ａが設けられている。これにより、テーパ部１４Ａがディフィーザと同様な機能を発揮し得るので、パイプ材１１の内圧が上昇した際に、パイプ材１１内の気体は、確実に外部に排出される。 On the extension direction main body portion 11B side of the first communication portion 14, a tapered portion 14A whose width direction dimension increases as it approaches the main body portion 11B is provided. As a result, the tapered portion 14A can exert the same function as the diffuser, so that when the internal pressure of the pipe material 11 rises, the gas in the pipe material 11 is surely discharged to the outside.

なお、第２連通部１５にも第１連通部１４と同様なテーパ部１４Ａが設けられている。これにより、パイプ材１１の内圧が上昇した際に、パイプ材１１内の気体は、確実に外部に排出される。 The second communication portion 15 is also provided with a tapered portion 14A similar to the first communication portion 14. As a result, when the internal pressure of the pipe material 11 rises, the gas in the pipe material 11 is surely discharged to the outside.

第１連通部１４は、溶接ビード部１１Ａと対向する位置にある。これにより、例えば、溶接ビード部１１Ａが挿入部１２と干渉することが回避されるので（図６参照）、挿入作業性が低下することが抑制され得る。 The first communication portion 14 is located at a position facing the weld bead portion 11A. As a result, for example, the welding bead portion 11A is prevented from interfering with the insertion portion 12 (see FIG. 6), so that the insertion workability can be suppressed from being lowered.
