Abstract
Official abstract text for this publication.
A park lock mechanism configured to restrict or allow a rotation of a rotating shaft includes a park pole configured to restrict the rotation of the rotating shaft and having a first inclined surface, and a park wedge having a second inclined surface capable of abutting on the first inclined surface and configured to move the park pole to a lock position that restricts the rotation of the rotating shaft, in which the park pole includes a protrusion protruding from a first side surface on a park wedge side in a moving direction of the park wedge, and the protrusion is formed so as to be continuous with the first inclined surface, and has a third inclined surface capable of abutting on the second inclined surface.
First claim
Opening claim text (preview).
The invention claimed is: 1. A park lock mechanism configured to restrict or allow a rotation of a rotating shaft, comprising: a park pole configured to restrict the rotation of the rotating shaft and having a first inclined surface; and a park wedge having a second inclined surface capable of abutting on the first inclined surface and configured to move the park pole to a lock position that restricts the rotation of the rotating shaft, wherein the park pole includes a protrusion protruding from a first side surface on a park wedge side in a moving direction of the park wedge, the protrusion is formed so as to be continuous with the first inclined surface, and has a third inclined surface capable of abutting on the second inclined surface, and the park pole includes a recess at a position corresponding to the protrusion on a second side surface opposite to the first side surface. 2. The park lock mechanism according to claim 1 , wherein a total length of the first inclined surface and the third inclined surface is longer than a length of the second inclined surface. 3. The park lock mechanism according to claim 1 , wherein an angle formed by the first inclined surface and the moving direction of the park wedge is larger than an angle formed by the second inclined surface and the moving direction of the park wedge. 4. A park lock mechanism configured to restrict or allow a rotation of a rotating shaft, comprising: a park pole configured to restrict the rotation of the rotating shaft and having a first inclined surface; and a park wedge having a second inclined surface capable of abutting on the first inclined surface and configured to move the park pole to a lock position that restricts the rotation of the rotating shaft, wherein the park pole includes a protrusion protruding from a first side surface on a park wedge side in a moving direction of the park wedge, the protrusion is formed so as to be continuous with the first inclined surface, and has a third inclined surface capable of abutting on the second inclined surface, and the park pole further has a fourth inclined surface formed so as to be continuous with the first inclined surface at a position adjacent to the protrusion on the first side surface. 5. A park lock mechanism configured to restrict or allow a rotation of a rotating shaft, comprising: a park pole configured to restrict the rotation of the rotating shaft and having a first inclined surface; and a park wedge having a second inclined surface capable of abutting on the first inclined surface and configured to move the park pole to a lock position that restricts the rotation of the rotating shaft, wherein the park pole includes a protrusion protruding from a first side surface on a park wedge side in a moving direction of the park wedge, the protrusion is formed so as to be continuous with the first inclined surface, and has a third inclined surface capable of abutting on the second inclined surface, the third inclined surface comes into contact with the second inclined surface before the first inclined surface when transitioning from the park lock release state to the park lock state, and a length of the third inclined surface is shorter than a length of the second inclined surface.
