The handle bar is provided with a hydraulic master cylinder 3, and a clutch lever 4 is swingably attached to a cylinder body 6 of the hydraulic master cylinder 3, and the clutch lever 4 is operated on the lower part of the cylinder body 6. A starter control switch 13 is installed that allows the engine to start when the clutch is disengaged.
When the clutch lever 4 is operated, the actuator 13b of the starter control switch 13 is stroked and the starter control switch 13 is turned on.

The starter control switch 13 is provided with a seal structure in order to prevent rainwater or the like from entering the interior. However, if the case itself is provided with a seal structure so as to cover the actuator 13b of the starter control switch 13, the starter control switch 13 13 becomes large, and the periphery of the clutch lever 4 becomes large, and the starter control switch 13 is increased in cost.
An object of the present invention is to reduce the size around the handle and reduce the cost of the switch device.

  The invention according to claim 1 has a connecting cord provided with a movable contact at one end of the cylindrical sleeve and a connecting cord connected to the fixed contact through a cord connecting portion at the other end, and operates the operating lever. Thus, in the switch device in which the movable contact comes into contact with the fixed contact, a seal member that seals between the inner periphery of the cylindrical sleeve and the outer periphery of the movable element is provided inside one end portion of the cylindrical sleeve.

  As a function, a seal member that seals between the inner periphery of the cylindrical sleeve and the outer periphery of the mover is provided inside the cap member that guides the mover, so that the switch is provided in comparison with the seal member provided on the main body side of the switch device. The device becomes smaller. Moreover, the special process etc. which arrange | position a sealing member in the main body side of a switch apparatus are lose | eliminated, or it decreases, and the cost of a switch apparatus is reduced.

The invention according to claim 2 is characterized in that a cap member for guiding the mover is provided at one end of the cylindrical sleeve.
As an operation, the seal member can be disposed in a dead space formed inside the cap member.

  In the invention according to claim 3, the cord connecting portion is inserted into the cylindrical sleeve from the other end portion of the cylindrical sleeve, and a retaining claw portion is formed on the outer peripheral portion of the distal end of the cord connecting portion. The side through hole is engaged with the provided side through hole to prevent the side through hole, and the side through hole is covered with a breathable sealing material.

  As an action, the cord connecting portion can be easily retained on the cylindrical sleeve by engaging the retaining pawl portion formed on the outer peripheral portion of the cord connecting portion with the side through hole provided in the cylindrical sleeve. Is done. In addition, the side through hole is used as a vent inside and outside the cylindrical sleeve, and the breathable sealing material prevents rainwater and the like from entering from the outside to the inside of the cylindrical sleeve. Is escaped to the outside.

According to a fourth aspect of the present invention, in the switch device according to the first or second aspect, the movable element is turned on and off by advancing and retreating by the operation of the operation lever, and the operation lever is supported in the operation lever holder. It is inserted and positioned in the provided through hole.
As an operation, the cylindrical switch device is inserted into a through hole provided in the operation lever holder, and is compactly stored and protected by the operation lever holder.

  According to a fifth aspect of the present invention, in the switch device according to the second or third aspect, the positioning portion is provided between the operating lever holder and the cylindrical sleeve so that the mounting position of the air-permeable sealing material is at the lower part of the cylindrical sleeve. It is provided.

  As an effect, the attachment position of the breathable sealing material is at the lower part of the cylindrical sleeve, so that rainwater or the like is less likely to enter the cylindrical sleeve through the side through hole located at the lower part of the cylindrical sleeve.

The invention according to claim 6 is characterized in that the attachment portion of the breathable sealing material penetrates the opening portion of the through hole of the operation lever holder along the outer peripheral portion of the cylindrical sleeve.
As an action, a ventilation passage is formed along the outer peripheral portion of the cylindrical sleeve in the attachment portion of the breathable sealing material and the opening of the through hole of the operation lever holder, so that the inside and outside of the cylindrical sleeve can be vented.

  In the invention according to claim 1, since the seal member that seals between the inner periphery of the cylindrical sleeve and the outer periphery of the mover is provided inside the one end portion of the cylindrical sleeve, dirt and rainwater entering the inside of the switch device by the seal member. This eliminates the need to provide a seal member on the body side of the switch device while preventing intrusion of the switch device, etc., and reduces the size of the switch device and eliminates or reduces the processing on the body side of the switch device. And cost reduction of the switch device can be achieved.

  In the invention according to claim 2, since the cap member for guiding the mover is provided at one end portion of the cylindrical sleeve, the seal member can be arranged using a dead space formed inside the cap member. The switch device can be reduced in size, and the seal member can be protected by the cap member.
