Abstract

A damper device includes a first rotary member, a second rotary member, a plurality of coil springs, an intermediate member and a slide spring. The first rotary member is a member into which a power of an engine is inputted. The second rotary member is disposed to be rotatable with respect to the first rotary member. The plurality of coil springs are configured to be compressed between the first rotary member and the second rotary member. The intermediate member is configured to engage the plurality of coil springs and couple the plurality of coil springs together. The slide spring is disposed axially between the first rotary member and the intermediate member. The slide spring is configured to slide against the first rotary member. The slide spring is configured not to slide with respect to the intermediate member.

First claim

What is claimed is:

1. A damper device, comprising:
a first rotary member into which a power of an engine is inputted;
a second rotary member disposed to be rotatable with respect to the first rotary member;
a plurality of coil springs configured to be compressed between the first rotary member and the second rotary member;
an intermediate member configured to engage the plurality of coil springs and couple the plurality of coil springs together; and
a slide spring disposed axially between the first rotary member and the intermediate member, and configured to slide against the first rotary member and configured not to slide with respect to the intermediate member, the slide spring being formed independently of the intermediate member and being positioned on the intermediate member.

2. The damper device according to claim 1 , wherein
the second rotary member has a first body and a pressing part, the first body being disposed on an inner peripheral side of the plurality of coil springs, the pressing part extending radially outward from the first body and configured to press the plurality of coil springs,
the intermediate member has a second body and an engaging part, the second body being disposed on the inner peripheral side of the plurality of coil springs, the engaging part extending radially outward from the second body and configured to engage respectively with the plurality of coil springs,
the pressing part and the engaging part are disposed to be circumferentially aligned, and
the slide spring is disposed radially inward of the pressing part and the engaging part with respect to an axial position between the first rotary member and both of the pressing part and the engaging part.

3. The damper device according to claim 2 , wherein
the intermediate member has a protruding part protruding toward the first rotary member, and
the slide spring has a spring part and a restriction part, the spring part being configured to contact the first rotary member and the intermediate member, the restriction part being configured to engage the protruding part and restrict circumferential movement of the slide spring.

4. The damper device according to claim 3 , wherein
the slide spring is a wave spring, and
the spring part has a first convex part and a second convex part, the first convex part contacting the first rotary member, the second convex part being disposed circumferentially adjacent to the first convex part and contacting the intermediate member.

5. The damper device according to claim 1 , wherein
the intermediate member has a protruding part protruding toward the first rotary member, and
the slide spring has a spring part and a restriction part, the spring part being configured to contact the first rotary member and the intermediate member, the restriction part being configured to engage the protruding part and restrict circumferential movement of the slide spring.

6. The damper device according to claim 5 , wherein
the slide spring is a wave spring, and
the spring part has a first convex part and a second convex part, the first convex part contacting the first rotary member, the second convex part being disposed circumferentially adjacent to the first convex part and contacting the intermediate member.

7. The damper device according to claim 6 , wherein
the protruding part is an embossed part formed by embossing the intermediate member.

8. The damper device according to claim 5 , wherein
the protruding part is an embossed part formed by embossing the intermediate member.
