ABSTRACT:
An apparatus is provided for supporting a shift lever for a transmission the shift lever including a ball-like portion which is on the shift lever and has spherical surfaces of a fixed curvature at least on a part of the lower and upper sides. A receiving surface has a concave spherical surface of nearly the same curvature as the lower spherical surface of the ball-like portion and is in contact with the lower spherical surface, and a retaining surface has a concave spherical surface in surface contact with the upper spherical surface of the ball-like portion and holds the ball-like portion between the concave spherical surface and the receiving surface. A retaining member is installed from above to cover the ball-like portion, and an elastic displacement section is projectingly formed on the lower side of the retaining member to enclose the upper part of the ball-like portion and is elastically deformable in the radial direction of the ball-like portion. The retaining surface is formed on a part of the elastic displacement section which faces the ball-like portion. The ball-like portion is held in between the receiving surface and the retaining surface with the elastic force of the elastic displacement section, and a frictional force based on the elastic force acts as the shift-lever operating load.
