Abstract

A switch device includes a switch body that supports a lever operating portion, and a cylindrical fitting portion through which the switch body is attached to an attached portion. The fitting portion includes a plurality of elastic deformation portions elastically deformable by a clamping force of a clamping band member and a pressed-bulging portion bulging from an outer surface of a tip portion of the elastic deformation portions. The pressed-bulging portion is configured to locate at a contact position with the attached portion.

First claim

What is claimed is:

1. A switch device, comprising:
a switch body that supports a lever operating portion; and
a cylindrical fitting portion through which the switch body is attached to an attached portion,
wherein the fitting portion comprises a plurality of elastic deformation portions elastically deformable by a clamping force of a clamping band member and a pressed-bulging portion bulging from an outer surface of a tip portion of the elastic deformation portions, and
wherein the pressed-bulging portion is configured to be always in contact with the attached portion while being sandwiched between the clamping band member and the attached portion in a radial direction of the cylindrical fitting portion.

2. The switch device according to claim 1 , wherein the fitting portion comprises a notch as a vertical slit formed on a circumferential wall, and
wherein the elastic deformation portions are each sandwiched between two of the notch.

3. The switch device according to claim 1 , wherein the attached portion comprises a column post rotatably supporting a steering shaft of a vehicle.

4. The switch device according to claim 1 , wherein an inner surface of the pressed-bulging portion is configured to contact the attached portion by tightening by an annular member from outside.

5. The switch device according to claim 1 , wherein the pressed-bulging portion is configured to have a thickness greater than that of a base portion of the elastic deformation portions.

6. The switch device according to claim 1 , wherein an outside of the pressed-bulging portion contacts with the clamping band member, and an inside of the pressed-bulging portion contacts with the attached portion.

7. The switch device according to claim 1 , wherein at least most of the press-bulged portion is covered by the clamping band member.
