A plurality of receiving portions 3d, 3e, 3f are provided on the outer circumferences of the base ends 3c, 3c of the engaging arm, and at the same time elastically engageably engage with the receiving portions. By attaching the pressing member 9 which is elastically urged via the spring member 10 to the mounting seat 5, the engaging arm 3 is provided with a modest positioning function and a rotational resistance force is given. (The reference numerals in the figure are made to coincide with the reference numerals in the publication for convenience.).
【０００４】 しかしながら、この実施例に於いては、係合アーム３の受け部３ｄ、３ｅ、３ ｆとこれに圧接する押圧部材９との関係により、係合アーム３の自由な回転を適 度に阻止することができると言うものの、玉状の押圧部材９を係合アーム３の受 け部３ｄ、３ｅ、３ｆに常時圧接させるためにコイルスプリング１０や平座金１ １が必要となるので、構成上の部品点数が多くなると共に、押圧部材９を取付座 ５に組み込む場合に、まず取付座５に形成された貫通孔５ｃに押圧部材９を入れ 、次にコイルスプリング１０を貫通孔５ｃに嵌め込み、そして貫通孔の開口部に 平座金１１をカシメ止めしなければならず、非常に組み込みが面倒でかつ時間が かかると言う欠点があった。However, in this embodiment, due to the relationship between the receiving portions 3d, 3e, 3f of the engaging arm 3 and the pressing member 9 that presses against the receiving portions 3d, 3e, 3f, the engaging arm 3 can be freely rotated appropriately. Although it can be prevented, the coil spring 10 and the flat washer 11 are required to keep the ball-shaped pressing member 9 in pressure contact with the receiving portions 3d, 3e, 3f of the engaging arm 3 at all times. When the number of parts in the configuration is increased and the pressing member 9 is incorporated in the mounting seat 5, the pressing member 9 is first put in the through hole 5c formed in the mounting seat 5, and then the coil spring 10 is inserted in the through hole 5c. Since the flat washer 11 must be fitted and then the flat washer 11 must be caulked to the opening of the through hole, the assembly is very troublesome and time-consuming.
