[0047]

[0048] figure 1 A motorcycle 1 as an example of a straddle-type vehicle is shown. refer to figure 1 A motorcycle 1 includes front wheels 3 steered by handlebars 5 and rear wheels 4 driven by a power unit 10 including an engine. Hereinafter, a motorcycle may be simply referred to as a "vehicle".

[0049] Steering components including handlebars 5 and front wheels 3 are pivotally supported on a head pipe 20 formed at the front end of the body frame 2 so as to be steerable. A handlebar steering shaft (not shown) connected to the handlebar 5 is inserted through the head pipe 20 . A power unit 10 is disposed at the front and rear central portions of the vehicle body frame 2 . At the rear of the power unit 10 , a swing arm 6 is pivotally supported around a pivot shaft 6 a so as to be able to swing up and down. Between the front portion of the swing arm 6 and the rear portion of the body frame 2, a rear suspension (not shown) is attached.

[0165] Figure 14 is the sum of stroke sensor 235 of the second embodiment figure 2 Quite a cutaway view.

[0166] Such as Figure 14 As shown, the structure of the cover 280 in the second embodiment is different from that of the first embodiment described above. In addition, in the following description, the same code|symbol is attached|subjected to the same structure as 1st Embodiment mentioned above, and description is abbreviate|omitted.

[0167]

[0168] Such as Figure 14 and Figure 15 As shown, the cover 280 has: an axial seal 81, which is in close contact with the flange surface 58 in the axial direction; a radial seal 82, which is in close contact with the second shaft part 42 of the shaft 40 in the radial direction; 283, which is provided between the axial seal 81 and the radial seal 82, and can bend and stretch when the shaft 40 slides;

[0169] The flexion and extension portion 283 includes a plurality of (for example, three in this embodiment) turn-back ...

Abstract

The stroke sensor (35) of the present invention is provided with a cover (80), which allows the relative movement of the shaft (40) and the housing (50) and covers the shaft in the sliding area of ​​the shaft (40) and the housing (50). The sliding end (55a) on the protruding side of (40) is provided with a flange surface (58) extending radially outward from the sliding end (55a) on the housing (50), and is provided with a The axial seal (81) that the flange surface (58) is close to in the axial direction, and the stroke sensor also has a fixing part (90) that presses the axial seal (81) onto the flange surface (58). ).

Description

technical field [0001] The present invention relates to a stroke sensor and a straddle type vehicle. Background technique [0002] Conventionally, for example, there is a stroke sensor disclosed in JP-A-2009-250307. In this technique, a stroke sensor is provided on a lost motion mechanism. The idling mechanism includes: a pull rod inserted into the housing in a freely movable manner; a push-pull rod connected to the pull rod so as to protrude to the outside of the housing; Covered with a rubber hood. The housing-side end of the rubber cover is in close contact with the inner peripheral surface of the housing in the radial direction, whereby the housing is hermetically sealed (sealed). [0003] However, the sealing performance between the rubber boot and the housing depends on the pressing force acting on the inner peripheral surface of the housing by the elastic force of the rubber boot. Therefore, when the case swells or the elastic force of the rubber cover decreases d...
