Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a carrier such as a rear carrier of a tricycle or the like.

Tricycles using ultra-low-pressure tires called balloon tires are put into practical use, but when a rear carrier is installed to load cargo, vibrations from the frame are transmitted to the tricycle, so anti-vibration measures were taken. It is better to increase the mounting support strength of the rear carrier.The rear fender, which covers the left and right rear wheels under the rear carrier, is not supported by the frame below the rear carrier, but is supported only at the front. Considering that the rear fender is made of a synthetic resin plate, it tends to flutter, and there is room for improvement in its support.

The present invention has been made to improve the above-mentioned problems, and its purpose is to connect a carrier extending in the vehicle width direction that extends over two wheels to a bracket that hangs from the carrier and is tied to a frame member. A stay is disposed to support the frame member above the frame member and to connect the bracket and the vehicle widthwise extending portion of the carrier, and a stay is provided between the vehicle widthwise extending portion of the carrier and the stay tip portion. By sandwiching the fender and connecting it together, it is possible to provide anti-vibration support for the rear carrier, support for attaching the outer frame extension portion of the rear carrier to the strong frame side, and provide strong support for the rear fender so that it does not flap. It is an object of the present invention to provide a mounting structure for a carrier such as a rear carrier.
