Embodiment Construction

[0042]The fall-off preventing structure of the present invention will be described in detail based on the following embodiments. The fall-off preventing structure of this embodiment is a structure in which the first structure and the second structure are fixed by the anti-dropping pin. Falling off prevention structure. In the following embodiments, a description will be made based on components used for components mounted in a transmission of a vehicle. Specifically, the shifting and speed selection shaft is used as the first structure, and the inner joystick is used as the second structure. The shift and select shafts form part of the transmission mounted on the vehicle. For example, in a manual transmission that is a transmission, it is a member that converts the movement of a shift lever into an axial movement and a rotational direction of a position shift and a selector shaft to perform a shifting movement.

Abstract

The present invention addresses the problem of providing a retention structure capable of effectively retaining a retention pin. A retention structure is provided with: a shift-and-select shaft (1) having an affixation section (11); an inner lever (2) having an affixation hole 2a fitted to the outer periphery of the affixation section (11); and a retention pin (3) for connecting the affixation section (11) and the inner lever (2) when the affixation section (11) is fitted in the affixation hole 2a. Insertion holes (20) which are provided in the inner lever (2) and into which the retention pin (3) is inserted each have: a proximity section (22) which is a radially inner part of the insertion hole (20), the radially inner part including a portion in contact with the outer periphery of the affixation section (11), and which is located close to the retention pin (3); and an expanded-diameter section (21) which is the remaining part on the outer side and which is expanded in diameter to have a greater diameter than the proximity section so that the expanded-diameter section (21) is not in close contact with the retention pin (3).

Description

technical field [0001] The present invention relates to a fall-off preventing structure that prevents one from falling off from the other between two members. Background technique [0002] Conventionally, various structures have been proposed for fixing the two members. For example, in a vehicle transmission, when the shift fork is fixed to the shift fork shaft, or the inner lever is fixed to the shift and speed selection shaft, after one part is spline-fitted with the other part, the anti-lock The pin is inserted into the through hole passing through the two. [0003] Here, the anti-dropping pin is pressed into the through hole to securely connect the two parts. In this case, a slotted pin capable of expanding and contracting in the radial direction is used as the drop-out preventing pin (Patent Document 1, etc.).
