- the hemispherical protrusion 25b realizes smoother sliding with respect to the inclined surface 71b.
- the plurality of protrusions 25b are arranged so as to be symmetrical around the button hole 71a when viewed from the outside of the front cover 71. Therefore, the switch device 10 can be stably held with respect to the front cover 71 in a state in which the protrusion 25b is in contact with the inclined surface 71b.
- the protrusion 25b is arranged at a position shifted from the opening 29 when viewed from the direction in which the resin button 30 is pressed. That is, the protrusion 25b is disposed at a position where it is difficult for the button holding portion 25 to be deformed. For this reason, the position of the protrusion 25 b with respect to the front cover 71 is unlikely to change, and the switch device 10 is stably held with respect to the front cover 71.
- the inclination angle of the inclined surface 25a of the seal member 20 is substantially the same as the inclination angle of the inclined surface 71b of the front cover 71. Therefore, even when an excessive force is applied to the protrusion 25 b of the seal member 20, the inclined surface 25 a of the seal member 20 comes into contact with the inclined surface 71 b of the front cover 71, so that the switch device 10 is moved against the front cover 71. It can be held stably.
- the resin button 30 including the protrusion 32 is formed of a cured resin, it is difficult to be deformed by an external force. Therefore, the resin button 30 is further reliably prevented from passing through the button hole 71a and dropping out of the front cover 71.
- the protrusion 32 and thus the resin button 30 can be more reliably held by the button holding portion 25.
- the protrusion 32 has a larger outer diameter than the button hole 71a when viewed from the outside of the front cover 71, but the outer diameter of the protrusion 32 may be smaller than the button hole 71a.
- the protruding portion 32 when viewed from the direction in which the resin button 30 is pressed, the protruding portion 32 may be formed so as to be disposed in a region surrounded by the button hole 71a.
- the resin button 30 is held by the button holding part 25 by fitting the protrusion 32 to the button holding part 25.
- the button holding unit 25 may not hold the protrusion 32.
- protrusions 25b are formed on each inclined surface 25a, but the number of protrusions 25b is not limited to this.
- each protrusion 25b is formed in a hemispherical shape, but may have other shapes such as a pyramid, a cone, a cylinder, and a prism.
- the button holding part 25 is formed only at both ends in the longitudinal direction of the base part 24, but the formation area of the button holding part 25 can be changed as appropriate.
- the button holding portion 25 may be formed over the entire edge portion of the base portion 24.
- the plurality of protrusions 25b are formed as contact parts so as to contact the inclined surface 71b.
- the protrusions 25b are omitted, and the entire inclined surface 25a contacts the inclined surface 71b. It may be formed. In this configuration, since the contact area between the inclined surface 25a as the contact portion and the inclined surface 71b increases, the holding force of the switch device 10 with respect to the front cover 71 can be improved.
- the resin button 30 is formed of a cured resin, but may be formed of rubber or the like that is easily deformable against an external force.
- the resin button 30 is formed in a substantially elliptical column shape, but may have other shapes such as a substantially cylindrical shape and a substantially prismatic shape.
- the plate 60, the housing 40, etc. in the above embodiment can be omitted as appropriate.
- the switch device 10 is applied to the door handle, but may be applied to other locations. That is, the switch device 10 may be applied to a switch device assembly other than a door handle, including a cover having a button hole and the switch device 10.
