摘要： When forming spray deposit (28) on the end face (23B') of a boss base material (23'), first, an inner mask member (32) is fitted to the prepared hole (23A') of the boss base material (23') and an outer mask member (33) is fitted over the outer peripheral side of the boss base material (23'). Then, a hard material is sprayed onto an annular deposit forming surface (23B1') between the inner mask member (32) and the outer mask member (33) and included in the end face (23B') of the boss base material (23') to thereby form a spray deposit (28). Accordingly, a portion acting as a working allowance for the prepared hole (23A'), out of the end face (23B') of the boss base material (23'), can be left intact as a spray-deposit (28)-free non-deposit-forming surface (23B2'), thereby preventing the spay deposit (28) from being damaged such as cracking when the prepared hole (23A') of the boss base material (23') is worked by a bite or the like.

摘要： A vehicular body oscillating mechanism (31) is provided between a frame (3) of an automotive vehicular body (2) and a stabilizer (18) thereby to sway the vehicular body (2) arcuately in a rightward and/or leftward direction about a pivot point (A) between right and left rear wheels (6, 7) when the stabilizer (18) is set on the ground for a load handling operation. This means that, after the stabilizer (18) is set on the ground for a load handling operation, the vehicular body (2) can be swayed arcuately laterally in a rightward and/or leftward direction together with a load lifting mechanism (12). Therefore, at the time of a load handling operation with the stabilizer (18) set on the ground for stabilization of the vehicular body (2), it is possible to turn and move the load lifting mechanism (12) into a rightward or leftward direction to adjust the position or direction of lifted freight goods in case it is deviated from a specified unloading spot in a lateral direction. Namely, in a load handling operation, the load lifting mechanism (12) can be adjusted in a lateral direction to dump lifted freight goods exactly on a specified unloading spot.

摘要： Protective projections (26D) which are provided on cylinder mounting brackets (26) of a cargo handling tool (21) are arranged to project toward a vehicle body (2) from behind the cargo handling tool (21). When the vehicle body (2) is driven in reverse direction with a boom (12) in a folded position on the side of the ground, the protective projections (26D) are collided against obstacles (A) on the ground prior to a rod (27C) of a fork cylinder (27) if the lower side (2A) of the vehicle body (2) has passed over and clear of the obstacles (A). Thus, the protective projections (26D) function to protect the fork cylinder rod (27C) of the fork cylinder (27) against direct collision against obstacles (A) on the ground.

摘要： A dust seal (20) is provided with a tubular fitting portion (20A), a bush end surface abutting portion (20B), a lip portion (20D) and a sealing projection (20E) integrally formed. The sealing projection (20E) is formed to project in an axially opposite direction to the lip portion (20D) from a radial inner section of the bush end surface abutting portion (20B) and abuts against a chamfered portion (14E) of a bush (14) in such a manner as to overlap the chamfered portion. Therefore, at the time of supplying lubricant such as grease between the bush (14) and a connecting pin (17), the sealing projection (20E) can prevent a part of the lubricant from entering between an end surface (14D) of the bush (14) and the bush end surface abutting portion (20B) of the dust seal (20) to maintain a sealed state therebetween. In consequence, the dust seal (20) can be stably held on the inner peripheral side of a boss member (12), preventing the pulling-out of the dust seal (20) by a lubricant agent supplying pressure.

摘要： In this grease composition, a grease produced by mixing at least one base oil selected from a mineral oil-type lubricant base oil, a synthetic lubricant base oil, and a biodegradable lubricant base oil with a thickener is compounded with a wax and water, and an additive such as a surfactant and a defoamer is optionally compounded therewith. A soap containing a calcium sulfonate complex is used as the thickener. A carnauba wax is preferably used as the wax. Since this grease composition is mainly composed of a grease and a wax, the grease composition extremely facilities its removal operation after application, is environmentally friendly, and has extremely excellent anti-corrosion performance. When the grease composition is used by being applied to a base material of an object to be welded, an effect of preventing the adhesion of welding spatters can be obtained.
