It relates to a garbage truck equipped with this.

  2. Description of the Related Art Conventionally, there has been known a garbage collection vehicle in which a dust input box equipped with a dust loading device is connected to a rear opening of a dust storage box mounted on a vehicle body so as to be tiltable. Also, after holding the garbage container containing the dust on the support stand at the rear of the dust input box of such a garbage truck, the support stand is lifted upward together with the dust container, and the upper opening of the dust container is the upper part of the dust input box. 2. Description of the Related Art There is known a garbage collection vehicle equipped with a garbage container reversing device that throws garbage in a garbage container into a garbage container by reversing it to a position facing a charging opening.

  By the way, there are a plurality of types of waste containers that are turned over by a reversing device and into which the waste is put. For example, a garbage container of a type (hereinafter referred to as “Type A”) in which an engagement recess is formed at the upper part of one side and a locking pin is arranged at the lower part, or a lashing bar is provided on the side of the middle part of one side. There is a garbage container of a type (hereinafter referred to as “type B”) disposed so as to protrude. Therefore, as described in Patent Document 1, for example, a garbage container reversing device provided with at least two securing means for securing and holding garbage containers of different types to be secured is developed.

  The garbage container reversing device described in Patent Document 1 is a first lash holding device that holds and holds a type A garbage container composed of an upper locking piece and a lower locking piece provided above and below a support base. A waste container of type B comprising a substantially inverted J-shaped upper clamping member pivotally supported on a support base via a bracket and a substantially V-shaped lower clamping member pivotally supported via the bracket And a second lash holding device for holding the lash.

  Further, in this waste container reversing device, a support roller is rotatably supported by a lower portion of the support base via a bracket, and supports the side of the waste container when the type B waste container is lifted and reversed. In addition to constituting the support member, it constitutes a relaxation means for relaxing the frictional resistance with the waste container when the waste container is supported. The support roller is rotatably supported by a shaft member whose base end is horizontally supported by the support base, and protrudes rearward from the support base to support the side surface of the waste container. And a storage position stored on the support base side.

  By the way, the garbage container reversing device can hold various types of garbage containers such as type A and type B in a fixed manner, and can invert them, and can put the garbage in the garbage container into the garbage throwing box. When the container is held and reversed, the frictional resistance may not be alleviated with only the support roller below the support base. For example, in Patent Document 2, a support roller is provided above the support base. However, since this support roller is fixed on the inner side (the side where the dust is thrown in), this is not the case after the dust container is inverted. There is no contact, and the relaxation of the frictional resistance is insufficient. In addition, when tying up a type B garbage container and turning it over, the type A garbage container lashing device interferes with one side of the type B garbage container, which not only deteriorates frictional resistance, but also in some cases. May destroy Type B waste containers.
