Problems solved by technology

[0004] However, although the above-mentioned conventional technology can suppress the breakage of the through hole, the shaft and the leaf spring will receive a large local load when the leaf spring is arranged between the through hole and the shaft, and there is a possibility that the shaft and the leaf spring will be damaged. Danger
Therefore, if a crack or scratch occurs on the shaft or the movable body, the fixed state of the movable body and the shaft will be broken, and the movement of the movable body will not be performed correctly.

Abstract

The invention provides a control switch for automatic transmission. A movable body (10) of the control switch possesses a shaft portion (13) passing through bearing holes (4, 5) traversely arranged on a housing (1), simultaneously, the shaft portion (13) possesses a through hole (17) which passes through the shaft portion (13) along the axial direction of the bearing holes (4, 5), and the through hole (17) is provided with a protective sheet (60) molded by abrasion resistance material.

Description

technical field [0001] The present invention relates to a control switch for an automatic transmission. When the gearshift lever of the automatic transmission of an automobile is shifted, a control switch is generated to indicate the parking gear, the reverse gear, the neutral gear, the forward gear, the second gear and the first gear. The gear position signal. Background technique [0002] Conventionally, there has been provided, for example, a control switch for an automatic transmission disclosed in JP-A-2007-155068. The control switch for an automatic transmission includes a movable body that rotates in a case in response to a shift operation of a shift lever of the automatic transmission, and a movable contact is provided on the movable body. On the other hand, a plurality of fixed contacts that are in contact with and separated from the movable contact corresponding to the rotational position of the movable body are provided in the housing, indicating the automatic tr...
