害物監視装置はバンパーにボルトやナットで強固に固定
している。2. Description of the Related Art Conventionally, a rear obstacle monitoring device for a vehicle is often installed in a truck or a freight vehicle due to its function and performance. In these trucks and the like, vibration and impact are larger than in passenger cars, but the importance of the appearance is somewhat lower. Therefore, the rear obstacle monitoring device is firmly fixed to the bumper with bolts and nuts.
しかし、後方障害物監視装置を普通乗用車に設置する
場合は、ボルトやナットが見えると外観デザイン上で問
題となるため、これらが見えないように工夫する必要が
ある。However, when the rear obstacle monitoring device is installed in a normal passenger car, if the bolts and nuts are visible, there is a problem in the appearance design.
この発明の目的は、ボルト類が外部から見えず、外観

範囲とする。According to the sensor mounting device of the present invention, a cylindrical main body housing having a flange portion on one end and a screw portion on the other end is provided, and the sensor is accommodated in the housing. The main body housing is inserted into the mounting hole of the mounting plate to engage the flange with the front surface of the mounting plate. On the outer periphery of the main body housing, a nut screwed into the screw portion and an elastic sleeve pressed by the nut and pressed against the back surface of the mounting plate are provided. The contact surfaces of the elastic sleeve and the nut are formed as uneven surfaces each having a ridge in the circumferential direction. Further, the thread groove forming range of the screw portion of the nut and the main body housing is set to a range in which the screwing is released at a tightening position exceeding the proper tightening position of the nut.

となる。According to the configuration of the present invention, the main body housing is fixed by tightening the nut and clamping the mounting plate between the flange portion of the main body housing and the elastic sleeve. In this case, since the elastic sleeve and the nut are engaged with each other on the uneven surface in which the crests are arranged in the circumferential direction, loosening of the nut due to vibration or the like is prevented. Further, when the nut is tightened until it exceeds the proper tightening position, the nut comes off the threaded portion of the main body housing and becomes idle.

例えば２条程度のねじ溝が形成される範囲とする。As shown in FIG. 4, the nut 4 also has both end faces at each peak.
4a is formed on the knurled surface of the knurled shape arranged in the circumferential direction. The pitch of the peaks 4a is the same as the pitch of the peaks 7b of the packing 7. The reason why the ridges 4a are formed on both sides is to eliminate the directionality of the front and back of the nut 4. The thread groove forming range 4b of the nut 4 is limited to an intermediate portion in the axial direction, and when the nut 4 is tightened until it exceeds a proper tightening position, the nut 4 comes off the threaded portion 2b of the main body housing 2. The thread groove forming range 4b is
For example, the range is such that about two thread grooves are formed.

置されても意匠的に優れたものとできる。According to this configuration, the main body housing 2 is secured to the flange 2 a and the holding cylinder 6 of the elastic sleeve 3 by tightening the nut 4.
Is fixed to the mounting plate 1 by sandwiching the mounting plate 1 therebetween. Since the flange portion 2a and the holding cylinder 6 are formed on an inclined surface, the main housing 1 can be mounted horizontally on the inclined mounting plate 1. The nut 4 is arranged behind the mounting plate 1, and a flange portion is provided on the front surface of the mounting plate 1.
Since only 2a is located, the appearance is not impaired by the nut 4 or the threaded portion 2b of the main body housing 2, and the design can be excellent even when installed in a passenger car.

ナット４の緩み防止を確実にし、かつパッキング７の強
度向上を図ることができる。Since the packing 7 of the elastic sleeve 3 and the nut 4 are engaged with each other on the uneven surface where the peaks 4a and 7b are arranged in the circumferential direction, the nut 4 is prevented from loosening and coming off naturally due to vibration of the vehicle body or the like. The ridges 7b of the packing 7 are connected by connecting ridges 7c. For this reason, the deformation resistance of the ridges 7b is increased to prevent the nut 4 from being loosened and to improve the strength of the packing 7. it can.

とがなく、したがってねじ締めの信頼性が向上する。As shown in FIG. 4, the nut 4 has a thread groove forming range 4b only at the center portion. Therefore, when the nut 4 is tightened to a position beyond the proper tightening position, the nut 4 comes off the screw portion 2b of the main body housing 2 and becomes idle. Therefore, the screw portion 2b of the main body housing 2 and the like are not damaged. That is, no matter how strong the tightening is, the main body housing 2 is not damaged, and the reliability of screw tightening is improved.

き、前記の式の関係が充足される必要がある。Here, when the nut 4 comes into a rotating state after being unthreaded, the threaded portion 2b of the main body housing 2 is loosened by one lead. However, the packing 7 and the holding cylinder 6
Is restored from the contracted state by elasticity, the engagement between the nut 4 and the ridges 4a and 7b of the packing 7 is prevented from being disengaged, and the function of preventing the nut 4 from loosening is maintained. In order to maintain this engagement, it is necessary to satisfy the relationship of the above-described expression for each of the above dimensions d 0 to d 3 .

う効果がある。[Effect of the Invention] The sensor mounting device of the present invention is configured such that the flange portion of the main body housing accommodating the sensor is engaged with the front surface of the mounting plate and tightened from the back side of the mounting plate with the nut and the elastic sleeve. The screws and the like do not appear on the front surface of the mounting plate, and the appearance is not impaired. Further, since the elastic sleeve and the nut are engaged with each other on the concave and convex surface in which the crests are arranged in the circumferential direction, loosening of the nut due to vibration or the like is prevented, and firm fixing can be performed. In addition, when the nut is tightened until it exceeds the proper tightening position, the nut is detached from the threaded portion of the main body housing and idles, so that there is no breakage of the threaded portion due to excessive tightening, and the reliability of fixing can be improved. . The prevention of loosening and overtightening of these nuts has an effect that sufficient fixing reliability can be obtained even for a vehicle.
