Lever operation device

Abstract

The present invention provides a lever operation device whose size can be reduced. The lever operation device comprises: a movable support member that supports a base portion of an operation lever such that the base portion is pivotable along a first operation plane; a housing that supports the movable support member such that the movable support member is pivotable along a second operation plane, the second operation plane being substantially orthogonal to the first operation plane; an actuator holder attached to the base portion of the operation lever such that the actuator holder is rotatable along the second operation plane; a first actuator retained by the actuator holder with first elastic urging means provided therebetween; and a second actuator retained by the movable support member with second elastic urging means provided therebetween, wherein the inner wall of the housing is provided with a first cam surface and a second cam surface, the first actuator and the second actuator being in elastic contact with the first cam surface and the second cam surface, respectively. When the device swings facing to the operation lever along the first operation plane, the actuator holder and the base portion rotate together and when the device swings facing to the operation lever along the second operation plane, the movable support member and the base portion rotate together.

Description

technical field [0001] The present invention relates to a lever operating device suitable for a turn signal switch device or a wiper switch device of a motor vehicle. Background technique [0002] In a lever operating device used as a turn signal switch device or a wiper switch device of a motor vehicle, a cylindrical operating lever is protruded from a bracket fixed to a steering column or the like, so that the operating levers can be positioned approximately at right angles to each other. Swing operation within the two operating planes of the intersection. Furthermore, by selectively operating the operation lever along each operation surface, various operation signals corresponding to the operation direction can be output. [0003] As a support structure for the operating lever in such a lever operating device, there is conventionally known a structure (for example, refer to Patent Document 1) that includes a structure that supports the base of the operating lever so as t...

Problems solved by technology

[0006] However, in the above-mentioned conventional lever operating device, the first driving body elastically contacting the inner inner wall of the bracket and the second driving body elastically contacting the inner inner wall of the bracket are arranged substantially on the same straight line, thereby When the operation lever is operated along the first and second operation surfaces, a desired click feeling is produced, so there is a problem that the support structure of the operation lever cannot be designed compactly.

That is, in the above-mentioned conventional example, the mechanism portion for supporting the base of the operating lever so that a desired operation can be performed must be formed in a shape with a long depth, so there is a problem that it is difficult to reduce the size of the lever operating device.
