Further, the wheel 140A rotates from the mounting position toward the base end side of the web portion 133 so as to be separated from the inner surface 132N of the flange portion 132, and the wheel 140A does not come into contact with the lower end 132T of the flange portion 132 to the external G. You can move.

また、回動中心軸155は、ウエブ部133を基準としてフランジ部132の幅方向において下端132Tより離れた位置に設けられているから、回動腕部156を回動すると、装着位置から車輪140Aがウエブ部133の基端側に向かって内面132Nから離れるように回動し、車輪140Aが下端132Tに接触することなく、非装着位置である外部に移動することができる。 Further, since the rotation center shaft 155 is provided at a position separated from the lower end 132T in the width direction of the flange portion 132 with reference to the web portion 133, when the rotation arm portion 156 is rotated, the wheel 140A is moved from the mounting position. Rotates away from the inner surface 132N toward the base end side of the web portion 133, and the wheel 140A can move to the outside, which is the non-mounting position, without contacting the lower end 132T.

また、本体136に他方の車輪140が位置固定されていると共に、一方の車輪140Aが車輪140,140Aの間が開閉するように回動するから、構造簡易にして着脱が容易となる。さらに、他方の車輪140が位置固定されているから、装着時に先に車輪140をセットすることにより、装置の荷重をガイドレール131に掛けることができ、取付作業が容易となる。 Further, since the other wheel 140 is fixed in position on the main body 136 and the one wheel 140A rotates so as to open and close between the wheels 140 and 140A, the structure is simplified and the attachment / detachment is easy. Further, since the other wheel 140 is fixed in position, the load of the device can be applied to the guide rail 131 by setting the wheel 140 first at the time of mounting, and the mounting work becomes easy.

また、装着時にフランジ部132に対して、車輪140,140Aがそれぞれ好ましくは40〜50度の角度をなすから、図34の状態で、移動体135が上下方向の力、横方向外側に引っ張る力に対して、それぞれ対抗することができる。このためフランジ部132Aを上側又は下側にしてガイドレール131を取り付けた場合にも対応可能となる。 Further, since the wheels 140 and 140A each preferably form an angle of 40 to 50 degrees with respect to the flange portion 132 at the time of mounting, the moving body 135 has a vertical force and a lateral pulling force in the state of FIG. 34. Can be opposed to each other. Therefore, it is possible to handle the case where the guide rail 131 is attached with the flange portion 132A on the upper side or the lower side.
