no. 1 approach

[0050] First, the following will refer to Figures 1 to 4 The anti-vibration damper according to the first embodiment of the present invention will be described in detail.

[0051] figure 1 It is a side view of the anti-vibration damper of this embodiment. figure 2 is a front view of the anti-vibration damper of this embodiment, and shows along figure 1 The view obtained by the arrow in X1. image 3 is a bottom view of the anti-vibration damper of this embodiment, and shows along figure 1 The view obtained by the arrow Z in . in addition, Figure 4 is a bottom perspective view of the anti-vibration damper of this embodiment, and shows the figure 1 The view obtained by the arrow S in .

[0052] Such as Figures 1 to 4 As shown, the anti-vibration damper 10 is a cylindrical member extending along an axis C parallel to the x-axis and having a peripheral wall portion partially cut along the negative direction of the z-axis. Here, the anti-vibration damper 10 includes a c...

no. 2 approach

[0086] Next, further reference Figure 10 with Figure 11 An anti-vibration damper according to a second embodiment of the present invention will be described in detail.

[0087] Figure 10 is a front view of the anti-vibration damper of the current embodiment, and is in positional relationship with figure 2 corresponding to that shown. and, Figure 11 is a bottom perspective view of the anti-vibration damper of the current embodiment, and is in positional relationship with Figure 4 corresponding to that shown.

[0088] Such as Figure 10 with Figure 11 As shown, the main difference between the anti-vibration damper 50 of the present embodiment and the anti-vibration damper 10 of the first embodiment is that the first rib 56a, the third rib 56c and the fifth rib 56e of the first extension 14a And the second rib 56b, the fourth rib 56d and the sixth rib 56f of the second extension part 14b are changed in shape, and the rest of the structure remains the same. Therefo...

no. 3 approach

[0092] Next, further reference Figure 12 to Figure 15 An anti-vibration damper according to a third embodiment of the present invention will be described in detail.

[0093] Figure 12 is a side view of the anti-vibration damper according to the present embodiment. Figure 13 is a front view of the anti-vibration damper of this embodiment, and shows along Figure 12 The view obtained by the arrow in X1. Figure 14 is a bottom view of the anti-vibration damper of this embodiment, and shows along Figure 12 The view obtained by the arrow Z in . and, Figure 15 is a bottom perspective view of the anti-vibration damper of this embodiment, and shows the Figure 12 The view obtained by the arrow S in .

[0094] Such as Figure 12 to Figure 15 As shown, the main difference between the anti-vibration damper of this embodiment and the anti-vibration damper of the first embodiment lies in the shape changes of the central part 62, the first extension part 64a and the second exte...

Abstract

A vibration insulation damper (10, 50, 60) insertable into an internal circumferential portion of a coil spring (20) and extending in an axial direction thereof, the vibration insulation damper is provided with an elastic body (14a, 14b, 64a, 64b) having a conical or pyramid outer circumferential surface formed so as to be shortened in distance with respect to the axial direction toward an end portion thereof in the axial direction, and a rib (16a, 16b, 16c, 16d, 16e, 16f, 56a, 56b, 56c, 56d, 56e, 56f) protruding outward from the outer circumferential surface of the elastic body to be brought into pressured contact with the internal circumferential portion of the coil spring when the elastic body is inserted into the internal circumferential portion of the coil spring.

Description

technical field [0001] The present invention relates to an anti-vibration damper, and more particularly, to an anti-vibration damper mountable to a coil spring for a vehicle pedal device. Background technique [0002] A pedal device of a vehicle such as an automobile, such as a brake pedal device, is provided with a coil spring configured to generate a predetermined compressive force or tensile force based on a depression force of the pedal or a stroke position of the pedal applied by a driver. , thereby adjusting the downforce applied by the driver. Although coil springs are used in either a compression direction or a tension direction, it is believed that in either compression or tension use, adjacent wires wound to form a coil spring contact each other causing noise. [0003] In order to eliminate such noise generated in the use of compression or extension of such a coil spring, a structure in which an elastic body such as a rubber material is added to the coil spring ha...
