(Problems to be solved by the invention) However, in the conventional roller as described above, since the grease-filled nipple is attached to the lateral center of the boss portion so as to project laterally, the crawler jumps up. The stones or lumps of sand that have collided may collide with the nipple, or the crawler may interfere with the nipple, resulting in damage to the nipple. There is a problem in that it is easy to do so, and causes inconvenience when the grease is filled in the boss portion by the nipple.

(Operation) Then, the grease is passed through the through hole (14a) from the intermediate portion on the outer periphery of the boss portion (13) to the bearings (17) and (17) in the boss portion (13), and the bearing ( 17) (17) can be supplied directly to the cavity (A), and the bearings (17) (17) can be effectively lubricated together.
Further, the grease-filled nipple (19) is installed by being installed between a plurality of ribs (18) that reinforce and connect the outer periphery of the boss portion (13) and the side surface of the ring body (15) to each other. Therefore, the nipple (19) can be protected by the respective ribs (18), which can prevent damage accidents of the nipple (19) due to stones or clods jumped up by the crawler. This also makes it possible to reduce the risk that the jumping mud will adhere to the nipple (15).
Moreover, even if mud adheres to the nipple (15), the nipple (15) is not only directed in the radial direction, but also separated from the center of the boss portion (12) outward in the radial direction. Since it is attached to the outer peripheral portion of the boss (12) so as to be directed in the radial direction, the nipple (1
5) receives a large centrifugal force due to the rotation of the boss portion (12), and as a result, the mud adhered to the nipple (15), particularly the mud adhered to the tip opening is effective by the centrifugal force. Since the tip opening of the nipple (15) is oriented in the radial direction, even if mud adheres to this opening, the mud can be scattered by the centrifugal force, and therefore the opening It is possible to prevent the mud from remaining in the section, and as a result, it is possible to reliably seal the grease from the nipple (19).

The crawler (11) can also be used when working in wetlands.
Even if dirt or the like may be splashed and scattered by the above, since the nipple (19) is protected by the ribs (18), there is little risk that dirt or the like will adhere to the nipple (19). However, even if dirt or the like may adhere to the nipple (19), the nipple (15) still has the boss (12).
Since the nipple (15) is attached to the outer peripheral portion of the boss portion (12) radially outward from the center of the boss so as to be oriented in the radial direction, the nipple (15) rotates the boss portion (12). As a result, the centrifugal force associated with
The mud attached to the nipple (15), especially the mud attached to the tip opening, can be effectively scattered by the centrifugal force, and the tip opening of the nipple (15) is directed in the radial direction. Even if the mud adheres to the inside of the part, the mud can be scattered by the centrifugal force, and thus it is possible to prevent the mud from remaining in the opening, and as a result, the grease from the nipple (19) Encapsulation can be reliably performed.

(Effects of the Invention) As described above, in the roller of the crawler type traveling device according to the present invention, the boss portion is provided between the outer periphery of the boss portion (13) at the middle portion in the longitudinal direction and the side surface of the ring body (15). A plurality of ribs (18) (18) extending radially outward from the outer periphery of (13)
Is provided so as to project outward with respect to the side surface of the ring body (15), and the boss portion (13) is provided on the boss portion (13) from the outer periphery of the boss portion (13) between the ribs (18). ), A radial through hole (14a) penetrating the cavity (A) between the bearings (17) and (17) is formed, and the through hole (14) is formed.
Attach the grease-filled nipple (19) to the boss (13).
Since it is mounted so as to be directed in the radial direction of the above, and the grease enclosing nipple (19) is provided between the ribs (18), the nipple (19) can be directed in the radial direction and the nipple (19) Grease can be directly supplied to the cavity (A) between the bearings (17) (17),
Therefore, it is possible to effectively lubricate each of the bearings (17) (17), and the grease-filled nipple (19) is provided on the outer periphery of the boss portion (13) and the side surface of the wheel body (15). The nipples (19) can be protected by the respective ribs (18) because the ribs (18) are connected to each other to be reinforced between the ribs (18).
It is possible to prevent damage accidents of the nipple (19) due to stones or lumps of sand that are jumped up by the crawler, and also possible to reduce the possibility that the jumping mud adheres to the nipple (15). In addition, if the nipple (15)
Even if mud adheres to the nipple, the nipple (15) is not only directed in the radial direction, but also the outer periphery of the boss (12) is located radially outward from the center of the boss (12). Since the nipple (15) is attached to the portion so as to be directed in the radial direction, the nipple (15) is largely subjected to the centrifugal force due to the rotation of the boss portion (12), and as a result, the nipple (15). ), Especially the mud adhering to the tip opening, can be effectively scattered by the centrifugal force, and the tip opening of the nipple (15) is directed in the radial direction, so that the mud is present in this opening. Even if it adheres, this mud can be scattered by the centrifugal force, and therefore, it is possible to prevent the mud from remaining in the opening, and as a result, it is possible to reliably enclose the grease from the nipple (19). It can be done.
