Title:
POWER EQUIPMENT
Document Type and Number:
Japanese Patent JP2019019776
Kind Code:
A
Abstract:
To provide power equipment which has improved durability of an elastic leg part while preventing imprudent inertia movement upon starting/stopping, in consideration of such a problem that the so-called elastic leg having a weakened stiffness, which is prepared to be deformable in order to prevent the movement because a large inertia force is generated by brakes jammed-on a reciprocating mechanism and, thereby, the whole air-compressor is moved from an installation site, for example, upon the stopping although vibrations of a compression part during actuation are absorbed by an elastic connection part and are hardly transmitted to the tank side, in a portable and stationary air compressor having the compression part internally fitted with a reciprocating mechanism as a vibration source and a tank part.SOLUTION: A through-hole 20b which is penetrated in a direction intersecting with an actuation direction of an inertia force generated upon starting/stopping is provided on a stationary elastic leg part 20. The stiffness of the elastic leg part 20 is weakened by the through-hole 20b and the inertia force upon starting/stopping is efficiently absorbed.SELECTED DRAWING: Figure 4
