摘要： In a work machine 1, when on a travel plane S of crawler belts 21, a straight line passing a predicted travel point P1 distanced by a given distance from the crawler belts 21 and having the same angle as a maximum climbing angle θ relative to the travel plane S is assumed to be a first straight line L1, and a straight line connecting an installation position of the distance measurement sensor 6 and the predicted travel point P1 is assumed to be a second straight line L2, the distance measurement sensor 6 is positioned above the first straight line L1 and measures a distance from the installation position to a ground surface on the second straight line L2. The control device 5 calculates a height H1 of a predicted travel region T based on a measurement result of the distance measurement sensor 6 and a detection result of a turning angle sensor 8, and determines whether a height difference H3 between a height H1 of the predicted travel region T calculated and a height H2 of the travel plane S is equal to or greater than a threshold, and actuates a notification device when it is determined that the height difference is equal to or greater than the threshold.

摘要： [Problem] To provide an electromagnetic drive unit that reduces the number of processing operations of an inner housing and also reduces manufacturing cost, and to provide a method for manufacturing this electromagnetic drive unit. [Solution] An electromagnetic drive unit according to the present invention includes an inner housing (H), a plunger (3) housed in the inner housing, and a solenoid assembly (SA) mounted to surround the inner housing. The inner housing (H) includes a stator (1), a yoke (2), and a cylindrical member (5). The inner housing is formed as follows. The cylindrical member and the yoke are bonded by welding in a state where one end side of the cylindrical member is fitted in a first level difference portion (2e). The cylindrical member and the stator are bonded by welding in a state where another end side of the cylindrical member is fitted in a second level difference portion (Ig).
