and a rear wheel speed machine connected to an output shaft; the front of the power unit thus formed forms a pair of left and right hangers that pass horizontally. The pivot allows these hanger arms to be rotatably connected to the frame. A two-wheeled locomotive is installed between the frame and the power unit to buffer the device from swinging up and down, especially to stand on the stand. Improvement of the stand bracket device of two-wheeled locomotive for power unit. [Prior art] In a two-wheeled locomotive, a person who mounts a standing bracket on a power unit, such as the one disclosed in Japanese Patent Laid-Open Publication No. 5-2 4 6 3 5 9 has been described [Inventive Content] Problem to be Solved) Installing a stand bracket on the power unit, for example, can be integrated with the crank of the engine to stand the stand bracket to support the hub. It is more advantageous to weld the stand bracket on the frame to support the installation of the hub. . However, when a standing stand is installed on the power unit, the weight of the stand will affect the load of the rear bumper, that is, the load under the spring will increase. Therefore, when the standing stand is installed on the power unit, it is strongly required that the stand be lightweight. The present invention has been completed in view of this situation, and an object thereof is to provide a bracket device for a two-wheeled locomotive that can reduce the weight of the bracket as much as possible and can be simply mounted on a power unit. (Means to solve the problem) 312 / Invention Specification (Supplement) / 92-07 / 92112832 The arm is, after being slowed down, the box is more expensive than the original one. In order to achieve the above-mentioned object, the present invention is to provide a pair of left and right hanger arms at the front portion of a power casing formed by: an engine; and a transmission connected to a rear wheel on a shaft; Wait for the hanger arm to be rotatably connected to the frame, and to install a rear bumper that can buffer the device from swinging up and down. In this car, on the base of the pair of left and right hanger arms, A pair of left and right standing brackets are formed side by side to form a spaced apart pair of bearing portions supported on the aforementioned pivot of the frame arm. These stand brackets support the hubs to be connected by a support shaft to make the standing upright position and Rotating between the storage positions is its first special feature, and the aforementioned casing and pivot are respectively corresponding to the crank case 10 and the second pivot in the present embodiment described later. According to this first feature, since the left and right hanger arms are integrally formed on the housing by a large distance between the left and right bearing portions of the pivot, the support of the power unit can be improved by the pivot, and the power unit can be provided. I often shake my posture from above and below for a good ride. In addition, on the two hanger arms, a pair of left and right standing stand supports are supported by a support shaft. Therefore, it is not necessary to form a standing stand support wheel on the outer shell to simplify the shape of the outer shell, which can be further sought. The cost of casting is reduced. In particular, the rigid bases of the left and right hanger arms of the left and right standing bracket support wheels are formed side by side at a narrower distance than the two bearings. Therefore, the bases of the standing supports supported by the hubs supported by these stands can be used. The end is made narrower 312 / Invention Specification (Supplement) / 92-07 / 92112832. The pivot of the casing placed on the output causes the two turbines of this force device to be narrowed (boss) by these suspensions. Sign. The implementation force of Ming is obtained by the rigidity of the power pack, and the good body can be obtained by holding the hub and the hub, which can be facilitated. The hub is spaced by the stand width of the stand, and 6 593028 can reduce the weight of the stand. . Therefore, the load on the rear bumper can be reduced and the riding feeling can be improved. Furthermore, in addition to the first feature of the present invention, the hub of the standing stand supported by the support shaft is arranged between a pair of standing stand supporting bosses. This is the second feature. According to this second feature, since the protruding surface of the standing bracket is arranged between the left and right standing bracket supporting bosses, a short protruding surface can be used, and the weight of the standing bracket can be further reduced. The protruding surface can be easily positioned between the two supporting brackets of the standing bracket, and the two supporting brackets of the standing bracket can be well assembled. In addition, in addition to the first or second feature of the present invention, a standing plate is provided with a reinforcing plate connecting the protruding surface and the left and right supporting feet, and a standing stand for abutting the reinforcing plate is formed on the hanger arm. The position stopper is the third feature. According to this third feature, the reinforcing plate connecting the protruding surface and the support foot can be used as a stopper plate that also serves as a standard stand-up stand, and the structure of the stand stand can be simplified. In addition, in the present invention, in addition to any one of the first to third features, the hanger arms on the left and right sides are formed in a narrow, splayed shape from the bearing portion toward the base portion at intervals on both sides in plan view. According to this fourth feature, the left and right hanger arms can increase the mutual rigidity in the lateral direction by the connecting pivot. At the same time, since the left and right standing brackets support the hub are formed on the narrow base between the two hanger arms, it is possible to Lighten the stand stand and achieve strong support for the stand stand. 7 312 / Invention Specification (Supplement) / 92-07 / 92112832 593028 [Embodiment] The following describes an embodiment of the present invention with reference to an embodiment of the present invention shown in the drawings.

They can be integrally formed on the crank case 10 and the second pivot shaft 15. The support rigidity of the power unit P can be improved, and the power unit P can be constantly shaken above and below the stable position, and a good riding feeling can be obtained. In particular, since the left and right hanger arms 17 are formed in a plan view and spaced from the bearing portions 17 a and 17 a toward the base, they become narrow and slightly splayed. Therefore, the second pivot The state in which 15 is connected to the suspension ring 13 increases the mutual rigidity in the horizontal direction, and further strengthens the supporting rigidity of the power unit P. In addition, since the two hanger arms 17 and 17 are integrally formed with a pair of left and right standing bracket support hubs 19 and 19 that support the protruding surface 22 of the standing bracket 9 by a support shaft 25, the crank case 1 It is not necessary to form a standing bracket to support the wheels 19, 19 on 0, but the shape of the crank case 10 can be simplified, and the casting can be further facilitated and the cost can be reduced. Moreover, the left and right standing brackets support Luyi 19 and 19 because the left and right hanger arms 17 and 17 have a relatively high rigidity at a narrower interval than the distance L1 between the two bearing portions 17a and 17a. It is formed by the arrangement, therefore, the base end portion of the standing bracket 9 connected to the hubs 19 and 19 by the stand 11 312 / Invention Specification (Supplement) / 92-07 / 921] 2832 593028 With a narrower width, the standing support 9 can be made lighter and the standing support 9 can have strong supportability. At this time, especially the protruding surface 22 of the standing bracket 9 is arranged between the two standing bracket supporting hubs 19 and 19. Therefore, the short protruding surface 22 can be used, and the weight of the standing bracket 9 can be further reduced. At the same time, The protruding surface 22 can be easily positioned between the two standing bracket holding hubs 19 and 19, and the two standing support supporting hubs 19 and 19 have good assemblability to the standing bracket 9. Furthermore, in the standing bracket 9, since the front protruding plate 22 and the connecting projection 22 and the supporting feet 21 21 abut against the standing stop of the crank case 10, the standing position A of the standing bracket 9 is regulated. The reinforcing plate 23 can also be used as a stopper plate, and the structure of the standing bracket can be simplified. The present invention is not limited to the embodiments described above, and various design changes can be made without departing from the scope of the gist. (Effects of the Invention) According to the first feature of the present invention as described above, a pair of left and right hangers are formed on the front of the power unit outside the front portion of the power unit constructed by the engine; and the transmission with the rear wheels connected to the transmission shaft. The arms can be rotatably connected to the frame through a horizontal pivot. A rear bumper can be installed between the frame and the power unit to buffer the device from swinging up and down. In a locomotive, a pair of left and right standing brackets are integrally formed on the base of the pair of left and right hanger arms at a narrower interval than a pair of bearing portions supported by the pivots of the hanger arms. Supporting the hub, waiting for the standing bracket to support the hub with the support shaft to make the standing bracket in the upright position 31W Invention Manual (Supplement) / 92-07 / 92112832 into a stand while the bracket 29 is changed out of the shell. 12 593028 rotates between the storage position. Therefore, the left and right hanger arms can be integrated on the housing of the moving device by taking a large distance supported by the left and right bearing parts of the pivot. Increase motivation Supporting the opposite, the power plant can impart stability of the posture is often shaken up and down, the good ride feeling can be obtained. In addition, on the two hanger arms, since there is a pair of standing bracket support hubs that support the left and right pair of standing brackets through a support shaft, it is not necessary to form a standing bracket support hub on the casing to make the shape of the casing. The simplification can further facilitate the casting and reduce the cost. In addition, since the left and right standing bracket support hubs are formed by juxtaposing the right hanger arm with a relatively rigid base at a narrower interval than between the two bearing portions, it is possible to hold these standing brackets together. The base of the standing bracket of the wheel hub is made into a narrow width, which can reduce the weight of the standing support, reduce the load on the rear bumper, and improve its riding feel. According to the second feature of the present invention, in addition to the first feature, since the raised surface of the standing bracket supported by the support shaft is disposed between a pair of standing support hubs, the left and right standing brackets support the hub. Equipped with the protruding surface of the standing bracket, it can be used as a short protruding surface, which can further reduce the weight of the standing bracket. At the same time, it can support the hub on the two standing brackets to facilitate the positioning of the protruding surface, and the two standing brackets support the hub. Good assemblability for standing support. In addition, according to the third feature of the present invention, in addition to the first or second feature, the standing bracket is provided with a reinforcing plate connecting the protruding surface and the left and right supporting feet, so that the hanger arm is standardized to abut the reinforcing The stand of the board 312 / Invention Manual (Supplement) / 92-07 / 92112832 Effectively just reached the wheel can make the left partition stand feel and make the stand between the stand 13 593028 the stand stop of the stand up position of the stand therefore 1 connection protrusion The reinforcing plate between the face and the supporting feet can be used as a stopper plate that also regulates the standing position of the standing stand, and can simplify the structure of the standing stand. Furthermore, according to the fourth feature of the present invention, in addition to the first and third features, In addition to any one of the features, the left and right hanger arms are formed in an interval of both planes. The bearing portion becomes a narrow figure in a narrow shape toward the base. Therefore, the horizontal direction can be improved by connecting the left and right hanger arms and the frame shaft. Mutual rigid In addition, at the same time, because the left and right standing bracket support hubs are formed at the base of the narrow space between the two hanger arms, the standing bracket can be lightened and the standing bracket can achieve strong support.
