PROBLEM TO BE SOLVED: To simplify the structure of a main body and a spring mechanism to thereby reduce the cost.SOLUTION: A handle catch C is made up of a main portion P1 and a rear portion part P2. Grooves 106 and 206 having substantially arcuate sectional shapes are formed on the front surface of the rear portion part P2 and the rear surface of a hook lever 2 as attachment parts of a spring mechanism 3. The spring mechanism 3 is configured to include a pair coil spring receiving members 31 made of a synthetic resin material disposed so as to be movable in an inclination manner in the respective grooves 106 and 206 that are formed to have a semi-circular cross-section and a coil spring 32 whose both ends are engaged with the respective spring receiving members 31 and which is disposed in a compression manner between the rear portion part P2 and the hook lever 2.SELECTED DRAWING: Figure 10
【課題】本体及びバネ機構の構造を簡単にして、コストの低減を図る。【解決手段】ハンドルキャッチＣは本体部パーツＰ１及び背面部パーツＰ２からなる。バネ機構３の取付部として背面部パーツＰ１の前面及びフックレバー２の後面にそれぞれ断面略円弧状の溝１０６、２０６を形成され、バネ機構３は、略半円筒形に形成され各溝１０６、２０６に傾動可能に配置される合成樹脂材からなる一対のコイルスプリング受け部材３１と、両端を各コイルスプリング受け部材３１に係止されて背面部パーツＰ２、フックレバー２間に圧縮して配置されるコイルスプリング３２とにより構成される。【選択図】図１０
