この際、バネ部材17はバネ性を有しているため支持部25
を挟み込む。同時に、係合穴17bに第１の係合片25aが入
り込み、バネ部材17が支持部25にしっかりと係合する。As shown in FIG. 2, the leg portion 21 is pushed downward into the insertion hole 27 until the second engagement piece 21a projects to the back side of the mounting board 1. Then, the second engagement piece 21a is attached to the mounting substrate 1
And the mounting member 15 is supported in an upright state with respect to the mounting substrate 1. At this time, since the second engaging piece 21a is engaged in the direction in which the mounting member 15 is pulled out, the second engaging piece 21a does not come off. Further, the spring member 17 is inserted into the holding portion 25.
At this time, since the spring member 17 has a spring property,
In between. At the same time, the first engagement piece 25a enters the engagement hole 17b, and the spring member 17 is securely engaged with the support portion 25.
この状態で、挾持部23にシーズヒータ３を差込み取付
けができる。In this state, the sheath heater 3 can be inserted and attached to the holding portion 23.
このようにして、シーズヒータ３が取付けられると、

25にバネ部材17を取付けるようにしても良いことは言う
までもない。The order of the mounting operation of the sheathed heater 3 is not limited to the above-described process. First, the sheathed heater 3 is inserted and mounted in the holding portion 23, and then the leg portion 21 is engaged with the insertion hole 27, and
It goes without saying that the spring member 17 may be attached to 25.
［考案の効果］ 以上、実施例により説明したように、本考案のシーズ
ヒータの取付具によれば、シーズヒータを工具を用いな
くとも簡単に取付けることができるため取付作業も容易
になる。[Effects of the Invention] As described above with reference to the embodiment, according to the fixture for the sheathed heater of the present invention, the sheathed heater can be easily attached without using a tool, thereby facilitating the attachment operation.
また、取付部材及びバネ部材は第１及び第２の係合装
置により係合できるため、取付基板にしっかりと取付が
できる。Further, since the mounting member and the spring member can be engaged by the first and second engagement devices, the mounting member and the spring member can be securely mounted on the mounting substrate.
さらに、支持部の拡張をバネ部材の付勢によって挟み
込みながら取付状態を保つため、シーズヒータの熱膨張
による伸縮や衝撃を吸収しながら挾持できる。In addition, since the mounting state is maintained while the expansion of the support portion is sandwiched by the urging of the spring member, the support portion can be held while absorbing expansion and contraction and impact due to thermal expansion of the sheathed heater.
