A brake device includes: a damper; an advancing and retreating member; a support section; and wedge members. The support section is provided on an opposite side to the wedge members with respect to the advancing and retreating member, and is capable of supporting the advancing and retreating member on an application side in a drive direction. On one of the support section and the advancing and retreating member, there is provided a raised strip section which extends in a braking direction. On the other of the support section and the advancing and retreating member, there is provided a groove section which restricts movement of the raised strip section towards a release side in the drive direction, and restricts movement of the raised strip section to both sides in a widthwise direction orthogonal to the drive direction and the braking direction.
1. A brake device comprising:
a damper which applies a braking force to a braking target by advancing towards and contacting the braking target;
an advancing and retreating member which causes the damper to advance and retreat in a braking direction towards the braking target;
a support section which supports the advancing and retreating member in a manner enabling advancing and retreating in the braking direction; and
wedge members provided so as to be capable of advancing and retreating in a drive direction orthogonal to the braking direction, which are advanced to an application side in a drive direction towards the advancing and retreating member, to thereby cause the advancing and retreating member to advance towards a braking side in the braking direction, wherein
the support section is provided on an opposite side to the wedge members with respect to the advancing and retreating member, and is capable of supporting the advancing and retreating member on an application side in a drive direction,
on one of the support section and the advancing and retreating member, there is provided a raised strip section which projects towards the other, and extends in the braking direction, and
on the other of the support section and the advancing and retreating member there is provided a groove section which restricts movement of the raised strip section towards a release side in the drive direction, and restricts movement of the raised strip section to both sides in a widthwise direction orthogonal to the drive direction and the braking direction.
2. A brake device according to claim 1 , wherein a leading end of the raised strip section has overhang sections which extend in the widthwise direction relative to a base end, and the groove section has a shape that is widened at a bottom to correspond to the raised strip section.
3. A brake device according to claim 2 , wherein the raised strip section has a T-shaped cross-section, and the groove section has a T-shaped cross-section corresponding to that of the raised strip section.
4. A brake device according to claim 2 , wherein the groove section has a dovetail groove shape in cross-section, and the raised strip section has a dovetail shape corresponding to that of the groove section.
