As shown in FIGS. 3 to 5, the flange 41 sandwiched between the sockets 5 includes a plurality of axial projections P protruding in the axis X direction of the elastic member 4 and a plurality of axial projections P. And a plurality of recesses C formed therebetween. A plurality of axial protrusions P are provided in the circumferential direction of the elastic member 4. Further, the radial convex portion RP described above extends from the tip of the axial convex portion P in the axis X direction. The recess C formed between the axial projections P communicates with a recess extending in the axis X direction formed by the radial projection RP.

As shown in FIGS. 3 to 8, the axial convex portion P includes a long convex portion PL and a short convex portion PS having a smaller amount of protrusion than the long convex portion PL. The long convex portion PL and the short convex portion PS extend in the same direction toward one side in the axis X direction. In the present embodiment, as shown in FIGS. 4 and 6, the long convex portion PL and the short convex portion PS are directed from the base portion 46 located at the central portion in the axial X direction of the flange portion 41 to both sides in the axial X direction. It extends. In FIG. 6, the base portion 46 is a region between the bottom portion CB of the concave portion C on one side in the axis X direction and the bottom portion CB of the concave portion C on the other side of the flange portion 41 with the annular rib 45 interposed therebetween. Show.

In this embodiment, the long convex part PL and the short convex part PS are separated in the circumferential direction by the concave part C as shown in FIG. In this embodiment, the recess C is formed as a groove-like recess extending in the radial direction between the long convex portion PL and the short convex portion PS, as shown in FIG. It extends radially. In this embodiment, as shown in FIGS. 2A and 2B, there is a space between the socket 5 (the end surface of the socket 5) and the bottom surface CB of the recess C in a state where the elastic member 4 is accommodated in the socket 5. To do. Thereby, the contact area between the socket 5 and the elastic member 4 is reduced, and transmission of vibration is further suppressed. Further, in this embodiment, as shown in FIGS. 4 and 5, the outer periphery side recess C <b> 2 extending in the axis X direction and continuing to the recess C is formed on the outer periphery of the flange portion 41, thereby further reducing the contact area. ing.

When the elastic member 4 is accommodated in the socket 5, the long convex portion PL has an end surface (first end surface S 1 and first end surface S 1 and It is configured so as to be pressed and deformed in contact with one side of the second end face S2 and to shorten the length of the long convex portion PL in the axis X direction. More specifically, the length from the tip T of the long convex portion PL on one end side of the collar portion 41 to the tip T of the long convex portion PL on the other end side of the collar portion 41 is the end surface of the collar housing portion 51. The width (between S1 and S2) is also long. When the long convex portion PL is compressed in the axis X direction and is sandwiched in the flange housing portion 51, the elastic member 4 is stably supported in the axis X direction. Therefore, the casing cap 3 attached to the elastic member 4 is difficult to move in the axis X direction. Therefore, the stroke loss of the control cable 2 can be reduced, and the transmission performance of the control cable 2 is improved.

In the present embodiment, in the present embodiment, the concave portion C is provided with a constant width in the radial direction so that the distance from the adjacent short convex portion PS is predetermined, and the volume of the long convex portion PL is further increased. Therefore, as shown in FIG. 5, the cross section perpendicular to the axis X direction is fan-shaped. The shape of the long convex portion PL is not particularly limited as long as it can be deformed by being pressed by the end surface of the socket 5. In the present embodiment, a minute gap is formed between the radially outer surface of the long convex portion PL that forms the outer periphery of the flange portion 41 and the inner peripheral surface of the flange housing portion 51, and the socket 5 The contact area with the elastic member 4 is reduced.

The elastic member 4 has an end surface of the socket 5 (the first end surface S1 and the second end surface S2) so that the tip T2 of the short convex portion PS can relieve vibration of the casing cap 3 when the inner cable 21 slides. It is accommodated in the socket 5 so as to be in contact with at least one). The tip T2 of the short convex portion PS only needs to be in contact with the end surface of the socket 5 when the inner cable 21 slides, and is not in contact with the end surface of the socket 5 before the inner cable 21 slides. It doesn't matter. Further, the tip T2 of the short convex portion PS comes into contact with the end surface of the socket 5 when the inner cable 21 slides, and the vibration of the casing cap 3 is mitigated. The short convex portion PS is configured not to be compressed in the axis X direction, or is configured to have a smaller compression amount than the long convex portion PL. In the present embodiment, the short convex portion PS has the tip T2 of the short convex portion PS on the end surface of the socket 5 when the elastic member 4 is accommodated in the socket 5 and no load is applied to the elastic member 4. Although in contact, the length in the axis X direction is set so that the tip T2 of the short convex portion PS is hardly compressed. The short convex portion PS can have the same shape as the long convex portion PL except that the length in the axis X direction is shorter than that of the long convex portion PL. It is good also as a different shape. The shape of the long convex portion PL and the short convex portion PS is such that when the end surfaces of the long convex portion PL and the short convex portion PS are pressed by the socket 5, the tip side of the compressed long convex portion PL is the short convex portion PS. Abutting on the tip side, the bottom CB of the recess C, the side surface of the long convex portion PL in the direction around the axis X, the short convex portion PS side surface facing the side surface, and the one end side portion 44a (the operated portion B2 side) It is preferable from the viewpoint of vibration attenuation that the space is formed by the end portion) or the other end side portion 44b (the operation portion B1 side end portion).

The arrangement of the plurality of axial projections P including the long projections PL and the short projections PS is not particularly limited as long as the recesses C are provided between the plurality of axial projections P. In the present embodiment, as shown in FIGS. 3 to 5, the elastic member 4 has a plurality of long convex portions PL, a plurality of short convex portions PS, and a plurality of concave portions C, and the concave portions C are long. It is sandwiched between the convex part PL and the short convex part PS. When the plurality of long convex portions PL and the plurality of short convex portions PS are alternately arranged in the circumferential direction, and the long convex portions PL and the plurality of short convex portions PS are evenly arranged in the circumferential direction of the elastic member 4 Further, the anisotropy in the circumferential direction of vibration absorption can be suppressed. In the present embodiment, four short convex portions PS are respectively disposed between adjacent four long convex portions PL, and eight concave portions C are provided between the long convex portions PL and the short convex portions PS. However, the numbers of the long convex portions PL, the short convex portions PS, and the concave portions C are not particularly limited.

As described above, in the present embodiment, the flange portion 41 has the long convex portion PL and the short convex portion PS, and the tip T of the long convex portion PL is pressed against the end surface of the socket 5 to be deformed, and the short convex portion When the inner cable 21 slides, the elastic member 4 is accommodated in the socket 5 so that the tip T2 of the part PS contacts the end surface of the socket 5 so that vibration of the casing cap 3 can be mitigated. As a result, when the elastic member 4 shown in FIGS. 2A and 2B is accommodated in the socket 5, as shown in FIGS. The end surface (hereinafter referred to as end surface S1) is compressed and deformed to become hard, and the position of the collar portion 41 in the axis X direction is stabilized. Accordingly, the elastic member 4 is stably fixed to the socket 5 by the long convex portion PL, and is generated by the elastic member 4 (and the casing cap 3) moving in the axis X direction when the inner cable 21 is operated. The stroke loss of the inner cable 21 is reduced. Therefore, the transmission performance of the control cable 2 can be improved by the long convex portion PL. Moreover, since the short convex part PS is not compressed by the end surface S1 of the socket 5, or contraction is small compared with the long convex part PL, the elastic material of the short convex part PS is maintained in a flexible state. When the inner cable 21 slides, the end surface S1 of the socket 5 and the tip T2 of the short convex portion PS abut, or the abutted short convex portion PS is further pressed against the end surface S1 of the socket 5. The short convex portion PS has sufficient elasticity to alleviate the vibration of the socket 5 and the casing cap 3. Therefore, it is easy to attenuate the vibration transmitted to the elastic member 4. Therefore, the support device 1 of the present embodiment can have different functions for the long convex portion PL and the short convex portion PS, and can simultaneously improve the transmission performance of the control cable 2 and the vibration damping performance. .

As shown in FIG. 9B, when the tip T2 of the short convex portion PS is not in contact with the end surface S1 of the socket 5, the contact area between the socket 5 and the elastic member 4 is further reduced. In addition, vibration transmission is further suppressed. Further, when the long convex portion PL is pressed and deformed, the deformed portion of the long convex portion PL comes into contact with the short convex portion PS as shown in FIG. Is transmitted to the flexible short convex part PS, and the vibration is effectively damped. In this case, as shown in FIG. 9B, when the space is formed by the concave portion provided between the long convex portion PL and the short convex portion PS, the vibration is further attenuated by the space, The vibration damping effect of the entire elastic member 4 is enhanced.
