いる。2. Description of the Related Art The structure of a door roller of this type is provided with means for vertically adjusting an axle supporting a wheel and means for fixing the axle at the adjustment position. However, the structure is complicated. There are disadvantages in that the number of parts is large, assembly is troublesome, and costs are high. Therefore, a simple structure of a door car with a simple structure, easy assembly, and low cost has been proposed. Here, a configuration is adopted in which the wheels are supported so as to freely move up and down with respect to a door case via an adjustment shaft formed of an eccentric cam shaft capable of rotational adjustment, and the adjustment shaft is provided at the center thereof. Position, an axle portion as an eccentric cam shaft portion for supporting the wheel is provided, and at an eccentric position with respect to the axle portion,
A bearing portion rotatably supported by the door case is provided.

If the door is in a deviated position, the load on the sliding door or the load when opening and closing the sliding door causes the wheel to be attached to the adjusting shaft against the frictional resistance in the rotation direction between the adjusting shaft and the sliding door at the bearing. Through which a rotational moment is generated. For this reason, there is a possibility that the vertical adjustment position of the door wheel cannot be secured by the adjustment shaft as described above.

きる。According to the first and second aspects of the present invention, there is provided a door roller configured to move wheels up and down with respect to a door roller case via an adjusting shaft composed of an eccentric cam shaft capable of rotational adjustment. In the structure, the adjusting shaft is provided at the center thereof and provided with an axle portion as an eccentric cam shaft portion for supporting the wheel, and the door wheel case is eccentric with respect to the axle portion. A rotatably supported bearing portion is provided, and serrated engagement teeth are formed on the outer periphery of the bearing portion.The door case is provided on an inner periphery of a support hole for receiving the bearing portion. A prerequisite is a configuration in which saw-tooth-shaped engaging teeth that are detachably engaged with the engaging teeth are formed. Therefore, a simple structural improvement is provided in which the support portion is provided with serrated engagement teeth and the corresponding door wheel case side is provided with serrated engagement teeth which engage with and disengage from the engagement teeth. In addition, it is possible to secure the vertical adjustment position of the door roller while maintaining a simple structure.

係合歯１０４、１０５がばかになるということもない。In addition, when the adjusting shaft 101 is rotated to adjust the vertical position of the wheel 2, the rotating range of the adjusting shaft 101 is limited to the stopper protrusion 1 in the arc-shaped step portion 103F.
By setting one of the two end steps 103G to the raised position of the wheel 2 (down position of the sliding door) and the other to the lowered position of the wheel 2 (up position of the sliding door), 2 or the vertical adjustment position of the sliding door is the door case 10
3 can be seen from the outside, and the adjustment work is easy. By displaying a position display 6 such as a symbol or a letter indicating the vertical adjustment position of the sliding door based on the vertical adjustment position of the wheel 2 near the arc-shaped step portion 103F or the both-end step portion 103G on the front surface of the door case 103, the adjustment work is performed. It is easier and more reliable. In addition, there is no possibility that the engaging teeth 104 and 105 become ridiculous by rotating the adjustment shaft 101.

の弾性変形による回動調整も容易である。If the entire adjustment shaft is made of a hard synthetic resin having elasticity, the manufacture and the rotation adjustment operation are easy, but the adjustment shaft is easily bent and deformed, which hinders the rotation of the wheel 2. However, in the invention of claim 3, the metal pin 101-2 as a core shaft prevents the adjustment shaft 101 from being bent and deformed, and does not hinder the rotation of the wheel 2. Since the outer wall portion 101-1 as the outer cylinder shaft is formed of an elastic hard synthetic resin, the axle portion 101C as the eccentric cam shaft portion on the outer periphery and the engaging teeth 104 on the outer periphery of the bearing portion 101A are formed. The rotation adjustment by elastic deformation at the time of rotation between the engagement teeth 104 and the engagement teeth 105 is also easy.
